Blue Bossa

Blue Bossa Chord Sheet





Key = Cm

First four bars = Cm7 to Fm7 is up a fourth (cycle)
Second four bars = It's a (ii V i) in Cm (D to G to C) which also moves in fourths!
Whenever I see a half diminished chord I know it might be the start of a minor ii V progression.
Third four bars = It's another (II V I) in Db Major (Eb to Ab to Db). Notice we use capital letters for the chord numbering system for Major chords and lowercase letters for Minor chords.
Half diminished is not really anything to do with Diminished Chords and is basically a minor chord!
Final four bars = Returns to the (ii V i) in Cm (D to G to C)

Autumn Leaves by Joseph Kosma

Autumn Leaves - Analysis

This great tune contains musical principles which are essential knowledge when it comes to understanding Jazz harmony.

So I'm starting off by making some notes here simply looking at the information I have: I'm looking at the lead sheet and I can see that the key signature has one # (F#) which means that this piece is in the key of Gmajor / Relative Eminor.

The form of the song is AABC. I can also see the chord changes in each section are arranged by the cycle and move in fourths, eg, Am7, D7, G∆, C∆, F#ø, B7, Em

The first six bars are diatonic to the Gmaj scale. The very first bar/intro starts on an E and walks up to the Am7 followed by D7, G∆, C∆ and F#half dim are all in G major. Key of G maj ?

In the first few bars I can spot the popular jazz chord progression the major II-V-I with the Am7 acting as the II, the D7 as the V and the G as the I. However when we get to the 7th bar something happens. The B7 is not within the key of Gmaj. Now I can see that the B7 as opposed to Bmin7 is acting as a dominant V chord. If that's a V then you have to ask yourself what is II ? The F#half dim which is diatonic to Gmaj is now acting as the II which makes Em the I.
At this stage it would be useful to know the harmonic minor chord sequence:
(i)minmaj7 / (ii)min7b5 / (III)maj7#5 / (iv)m7 / (V)7 / (VI)maj7 / (VII)dim7
And also we need to know the E harmonic minor scale:
E F# G A B C D# E

So in the first four bars excluding the intro are in the key of Gmajor and in the next four bars we are in the key of Eminor. The 'B' section is made up of a minor ii-V-i (Em) and a major II-V-I (Gmaj).


  1. Any dominant 7th chord (B7 or D7 above) is always a V7 chord. But which one ?
  2. When preceded by a minor 7th chord (a 5th higher) the dominant chord is the V7 chord of a IIm7-V7 scale-tone chord segment of a major scale.
  3. When preceded by a half diminished chord (a 5th higher) the dominant chord is the V7 chord of a IIø-V7 scale-tone chord segment of a harmonic minor scale.

Chord Tones


Another Great Drill

Visualizing chord tones for instant recall

The reason it is difficult to name the 6th of a chord for you is because the chord tones are not sufficiently ingrained in your mind. No worries. The process of visualization will greatly aid in putting chord tones at your fingertips. Review this article on Visualization for jazz improvisation I wrote back in April. Follow the advice in that article to get started. Remember, visualization means seeing, hearing, and feeling the notes in your mind. Then do the following exercise:
Visualize the root of every major seventh chord around the circle of fifths aka “the cycle” (shown below).
cycle of fifths
Next, visualize the 3rd of every major chord around the cycle (shown below).
Cycle thirds
After the 3rd, continue by visualizing the 5th, then 7th, then the 9th, then the #11, and finally the 13th, all over the cycle just as in the previous examples. Do this for at least a week, everyday for 20 minutes before moving on. DO NOT BE IN A HURRY. The more solid this first group of exercises is, the easier all your future visualization will be.
Once you’ve got the chord tones solid on major, move to dominant seventh chords. If you did the majors well, then this should be really easy, as it’s just one note different (the flatted seventh) to get to a dominant quality (shown below). And yes, I never think of things like Cb, which technically over Db7 the seventh is Cb. I recommend simplifying these cases as I did in this example.
cycle dominants
After dominant, do minor seventh chords in the same manner all the way from root to 13th.
Once you’ve gotten minor in your head, do half-diminished.
And then finally go through the various alterations on a dominant chord. This includes: b9, #9, #5 (same as b6 or b13th), #4 (same as b5 or #11). Take a look at this article onalterations for some more in depth advice down that alley. Here’s an example of visualizing the #5 over dominant seventh chords around the cycle.
Cycle dominant #5
To recap, you’ll be visualizing each chord tone (1, 3, 5, 7, 9, 11, 13) one at a time, from a given chord quality around the cycle. Then, proceed to the next quality. The five chord qualities are: MajorDominantMinorHalf-Diminished, and Altered. Here’s all the chord tones for those qualities in the key of C. Notice over major and dominant I raise the 11th, as it is a more consonant sound.
Chord Tones

Chord tones over tunes

After visualizing chord tones over the cycle, try visualizing pairs of chord tones over a tune. I like to start with a blues for pretty much anything. Start with an easy pair like root and 3rd, and gradually progress to something more difficult like #5 and b9 as shown below.
Blues #5 b9
After you’ve visualized through all these exercises, play through them on your instrument paying close attention to how each chord tone sounds against the harmony. Once you feel pretty comfortable playing them on a blues, apply the same thinking to a tune you are working on. First visualize single chord tones, then pairs, then play single chord tones and pairs through the tune.

Ingraining chord tones is a journey

Take your time working through this stuff, as you can never know it well enough. Strive for daily perfection of small tasks. In this way, each day you will get closer to the multi-level goal: being able to instantly name any chord tone over any chord, knowing what that sound is in your mind, and knowing where the fingering to produce that sound is on your instrument.

Jazz Improvisation Drills

I Found these great improvisation drills on the web so I thought I would share theme here...

Visualization for Jazz Improvisation

Countless hours in the practice room and rhythm changes or a simple bridge to a tune still giving you a tough time? This is a familiar situation to everyone of all levels. I used to waste hours mindlessly practicing, thinking that there was some secret I was missing, or if I just kept improvising over the changes, I would eventually just get it. Or maybe it wasn’t the changes at all, but maybe it was something faulty with my equipment. Oh yes, that had to be it. If I could just get my hands on the right mouthpiece or that latest ligature then…that had to be it!!!
This attitude is completely delusional, yet many of us continue to think this way for years! Playing over a tune constantly, hoping that eventually you’ll play well over it is a mindless pursuit, as is blaming your equipment for your shortcomings as an improviser.
In actuality, the problem is not external. We hold in our mind what we will play before we even pick up our horn, therefore, to change what we are going to play, we have to change what’s stored in our mind. Sure, when you practice your instrument, your mind is altering its stored information, but what if you could simply go directly to your mind and start fixing the bugs? That is where visualization comes into the picture.

Defining Visualization

The dictionary defines visualization as the formation of mental images. For the purposes of this article, think of it as creating a mental image of chord tones and progressions in the mind’s eye, accompanied by a tactile and aural sense. Don’t worry if you don’t completely understand yet. It will become extremely clear as we progress.

Mental Roadblocks

Ok. So you’re soloing over a familiar tune and everything is going great. You’re feeling good and then all of sudden, you hesitate for a moment. You think to yourself, “What chord am I on?” By the time you figure it out, the chord is long gone. When your mind stumbles on a roadblock like that, your flow is broken and all sense of creativity is lost.
These roadblocks that exist in our minds are made up of lapses in time. They could be the time that it takes to know the chord you’re on, the right notes to play, where you are in a tune etc. They could be seconds long or they could be milliseconds. The point is that if they are there, that is bad.
Practicing visualization reduces the time it takes to recall elements of the tune, until they are ingrained in your mind. In time, these mental roadblocks will disappear. Then, when you do go to the practice room or the bandstand, you’ll be armed with the confidence to have a more productive, positive, and fun experience.

Removing Roadblocks

Gradually, one by one these roadblocks can be removed, until all that is left is a super highway of your own creativity. How do you do this? Start with the exercises below and practice them diligently everyday. They really don’t take much of a time commitment and the rewards are huge. I’ve written out an entire series of exercises that I put on my night stand and for fifteen minutes before I go to bed, I simply run through them. Once you get proficient in visualization, you’ll be able to do it anywhere and take advantage of the many segments throughout the day that you have a few minutes to kill.

Why Visualization is so Effective

When you are visualizing, your mind doesn’t know that your body is not actually engaging in the real activity. By working directly with your mind, as opposed to your body and then your mind, you are going straight to the source. Check out what Jerry Bergonzi says in his wonderful book which I highly recommend for anyone at any level, Melodic Structures:
“With the use of visualization, the mind actually teaches the body and the mind remembers what the body is more apt to forget. The mind visualizes what the body does in multi-dimensional fashion. It practices the fingerings and the notes, it hears the sound and the content, it feels the intention, the emotion, and the nuances of what is played. The body then follows suit. The body teaching the mind is actually a backward process and for this reason through the use of visualization we are able to learn more quickly. Wherever you have a difficult time mentally is where you will encounter problems playing on your instrument. Work it out mentally and you will no longer have these problems. With practice, whatever you are able to visualize you will then be able to play” (Bergonzi, 32).
Not convinced yet? Well you should be, but if that’s not enough, Bergonzi adds that “Very often ten minutes of visualization is equivalent to two hours of physical practice”(Bergonzi 32). With a return on your time like that, why wouldn’t you want to spend as much time doing this as possible?!

Getting Started with Visualization

It may take a few days to get comfortable visualizing, but after the initial phase, it will be easy. Start out with this simple exercise:
  1. Sit somewhere comfortable where you will not be disturbed. Later you will be able to do this anywhere, but right now use all the help you can get.
  2. In your mind’s eye, see the chord symbol for C Major (I try to keep things as simple as possible, so even for C major seven, I would just visualize the image below)
    C Major Chord Symbol
  3. Congratulations you just visualized! Easy right? Ok enough, celebration we’ve only just begun. Now see a music staff below the chord symbol
    C Major chord with staff
  4. Once you can clearly visualize the chord symbol with the staff, add the root of the chord to the picture.
  5. Now you are going to add an aural sense to the equation. Hear how you think that root sounds on that C Major chord. Often I hear piano and I try to hear a solid pitch. Don’t worry about the absolute pitch. I do not have perfect pitch, however, through these exercises, coupled with daily ear training, you will develop the necessary relative pitch to hear chord motion while visualizing. As you get more advanced, you will want to learn how to hear the chord in the background of the pitch you are focusing on as well.
  6. Next add a tactile sense. Feel exactly how it would feel to play that note on your instrument. If you play saxophone like me, at this point you will be seeing the image of the C Major chord symbol above a staff with the note ‘C’ on it, while you are hearing the note ring in your head, and feeling how it would be like to push the key down with your left middle finger.
So that is basic visualization. Here are some variations to try before moving on:
  • See, hear, and feel (all at the same time) different chord tones on the C Major chord. For example, after you have done the root, try the third, and then the fifth and so on, until you have visualized all the chord tones.
  • Try visualizing pairs of notes. A valuable pair as you would have guessed is three-seven. You could see them as a block chord or try seeing a half-note of the third and a half-note of the seventh.
    Third and Saventh on C Major
  • Experiment with groups of three, four, or even five notes. The possibilities are endless. Be creative!
Practice these steps until it is second nature to be able to see, hear, and feel chords and chord tones in your head simultaneously. When you feel confident, begin to apply these steps to some progressions.

Applying Visualization to Common Chord Progressions

Since the ii-V-I is so common, it is always a good place to start. In this exercise, we are going to visualize a ii-V-I in C major. Follow these steps to get a handle on visualizing through progressions:
  1. Again, sit somewhere where you won’t be bothered to avoid distractions while you are first starting out.
  2. First, see the chord symbols in your mind’s eye.
  3. Next add the staff
  4. Now add the roots of the chords to the picture
  5. Add the sound of each note and this time try to hear the chord in the background as well. Keep the note on the staff the prominent sound though.
  6. Feel the notes under your fingers as you progress from one chord to the next in time. (Yes, eventually you want to keep a consistent tempo through the progression)
  7. Now visualize half notes of the third and seventh of each chord, progressing in time from one chord to the next. Pay special attention to the transitions as the seventh of one chord goes to the third of the next.
  8. Loop step 7 until you can instantaneously ‘feel’ the chord tones, even before you arrive to them in the exercise. For instance, you are thinking of D-, yet you feel, see, and hear G7 before you even get there.
Visualizing the third and seventh as in step #7 is essential to hearing a progression operate in your mind’s ear. After practicing these resolutions, your ear will guide you through the changes much more smoothly. Your dependency on background tracks or comping instruments will diminish and you will feel much more confident.

Visualization Drills Based on Common Chord progressions

Here are some drills based on frequently encountered chord progressions. They are selected from the exercises that I run through each night and they continue to help me tremendously.

Endless Possibilities of Visualization

This is just a starting point. After working on these exercises for a while, start to create your own. Try experimenting with:
  • Different chord tone combos
  • Altered chord tones, b9, #9, b5, b13 etc.
  • Other chord progressions that you encounter frequently
  • Any progression that gives you a tough time
  • Blues changes
  • Rhythm changes
  • Standards you are working on
The possibilities of applying visualization to help you become a better improviser are literally endless. Have fun trying it out and stay tuned for plenty more about visualization in the future!

About Me

Thanks for checking out my Bass blog!
My name is David and I’ve been playing bass for about 25 years. I’m your typical bass player who over the years has played many popular songs in various live cover bands. It's really my love for music and my interest in music and my love for electric bass which led me to create this blog. What do I hope to gain from it? Well I hope that I will continue to learn from outside input which in turn may help other musicians along the way.

When I first started playing I learned enough theory and took enough lessons to set me off. 
As I said, I played in various cover bands but always thought I wasn't really making any real progress as a musician. As time rolled on it was like I had gained a fair amount of theory knowledge but when it came to actual playing, the theory and the practical were two completely different things. It was only after standing in on bass in a jazz band for a friend that the can of musical worms was opened. I accepted the two gigs without knowing exactly what I was letting myself in for. All in all it went tolerably well. I got off lightly because when the band leader gave me the chord sheets it seemed like fairly easy 12 bar format but boy did I sweat when those chord changes were coming at me. I'd never even heard of the songs even though now I know they are the Jazz Standards. I recall playing great tracks like summertime and chameleon without actually knowing anything at all about those pieces. Each time the sax player or the guitarist took a solo it focused the audience away from me at least. When they called for the bass solo I just smiled and kept playing through the chords whilst looking at the sax player to save me :) The second gig was better but I knew I was out of my depth and still no bass solo! After the two gigs I decided I didn't want to just struggle by, I wanted to learn about music and Jazz seemed to offer the perfect training ground where I could apply any new knowledge. I wanted to learn enough to be able to play comfortably.

The following week I sought out a local music teacher and was on my way to studying music theory. I think I was about 19 at the time. I then took and passed a Grade 5 theory examination to distinction. So here I was, armed with some good music theory knowledge with high hopes of eventually making some real progress as a player?

 So what can I hope to gain from this blog?

Well I hope to learn as much about music as I can, but more specifically I want to learn about jazz and how to function correctly as a bass player in a jazz band. I am hoping that whilst I learn, you can learn too and share knowledge.

Jazz is such an interesting form of music because of the way the great jazz musicians colour the chords and alter the scales. Much of it extends well beyond my basic understanding of music and it offers the chance to progress and move forward in a very musical and enjoyable way.

Jazz players used songs from the Great American Songbook as vehicles for jazz improvisation. They played the melodies instrumentally (or sang them if a vocalist was involved) at the start of the tune; this is called playing the head of the tune. Once that was done, the chords that formed the harmony of the song remained while the soloist improvised a new melody; this is called blowing on the changes. At the end, they'd play the melody one last time and that was it. Because jazz players favoured these songs so much, their melodies and harmonies became the foundation for jazz harmony. These songs became the songs that all jazz players know and play today; they are aptly referred to as standards.

For the moment I'm working my way through the great great standard, Autumn Leaves. A much recorded popular song. Originally a 1945 French song "Les feuilles mortes" (literally "The Dead Leaves") with music by Hungarian-French composer Joseph Kosma and lyrics by poet Jacques Prévert.


So head over to 'Autumn Leaves' in my blog and feel free to comment and correct where appropriate on my analysis of this great song.

Thanks for reading,

David.
