We spent six lessons on classical improvisation taking us from a simple one-note improvisation to a beautiful classical improvisation over the chords of Satie’s Gymnopedie 1.
Often, a student has told me that their problem with jazz improvisation is that they don’t know all the scales yet.
It is as if they are looking for a shortcut. “If I only can memorize the major and minor scales and a few modal scales, I’m set to go!” Then, they get discouraged because that is a big task.
You can improvise even if you don’t know all the scales! The more scales you learn, the more material you have for improvisation, but, the reality is that for every scale you learn and explore, you will soon discover there are many more yet to learn and explore. You will never know all the scales, but that is okay. Use what you have.
If you are feeling comfortable with the more classical sounding major and minor scales, start with some modes.
I love ii-V-I progression improvisation and it is so useful in jazz and a great place to start using three scales: Dorian, Mixolydian, and Major (Ionian). It is a great place to begin to expand your improvisational vocabulary.
Of course, other places to explore would be the major and minor blues scales.
Our ability to communicate verbally is a lifelong process and the same can be said about our musical communication through improvisation. Just keep exploring and learning. In the meantime, improvise using what you know even if it is only one-note!
