It always helps me to have or make a chord chart of whatever tune I'm working on improvising on.As I like to say at workshops, even if you're playing "Happy Birthday", make a
chart. The goal here is to have a visualization of the form of the tune--how the cadences connect, where the repeats are, how the form works(A-A-B-A, for example).Having that in your "mind's eye" makes it more difficult to lose your spot in the tune,and easier to focus on what notes to feature with specific tonalities.
Here's a "chart". Let's do Cole Porter's "Night and Day", which never ceases to amaze. I just heard a beautiful version on the radio by trumpeter Bobby Shew...
#Dm7b5 / G7b9 / C / C / Dm7b5 / G7b9 / C / C /
#F#m7b5 / Fm7 / Em7 / Eb dim / Dm7 / G7 / C / C /
Bridge or B section
# #Eb / Eb / C / C / Eb / Eb / C / C /
# F#m7b5 / Fm7 / Em7 / Ebdim / Dm7 / G7 / C / C /
Each slash-marked "box" equals a four-beat measure. Form is A-A-B.
The melody might run through your head as you play over these changes, but the goal for improvising is to come up with ANOTHER melody. Embellishing the original melody is fair game when initially stating the melody("playing the head, as the jazzers say..)or when re-stating the melody to close the tune's performance(sometimes called "taking it out"). #
Here's a chart for another really cool tune, The Cherokee Shuffle:
#A / A / A / F#m / A / A / A E7 / A /
bridge or B section:
# D / A / D / A / D / A / A / F#m / E7 / A //
#form here is A-A- B-B.
You'll undoubtedly find different versions of these tunes and cats will definitely jump all over whether these changes are right. The point here is the process, and I think making a chart and memorizing the tune's(harmonic) form are essential to improvising.
All the best and please have fun going for the good notes.
