I often hear that leading football players and baseball players write practice diary everyday since they were in elementary school.
Writing practice diary considerably increases efficiency also when you practice improvisation.
“Today I practiced what”
“Not good at two-five of Abm7Db7 so I have to practice.”
“In addition to Bb pentatonic phrases, G minor pentatonic phrase is also fits on this song.”
Like this, write whatever you think important things with you noticed.
My practice diary is like this.
I heard that “Recording Diet” which records only what you ate is very effective..
In this way, Not PCs, use their own hand written in pencil and a notebook,
recognizing with your eyes let the brain firmly recognize so it’s vey effective to learn a musical instrument.
Start practicing after seeing the diary written on the previous day makes that you can avoid the situation like…
“What should I practice today??..well, anyway let’s practice something.
But I don’t know what is good practice. It’s just wasting time and lose motivation, so will quit practicing today.
My improvisation didn’t improve today as well just like yesterday”
You can save the previous playing level
Also jazz, you can improvise inmany different approaches against the same placewith assuming various chord progressions and useable scale in the same chord progression.
By recording what you analyzed yourself, you can clear your thinking like what approaches and phrases fit on this song,
so you can take advantage of when a similar chord progression came out in other songs.
It’s benefits of practice diary that you can start practicing as played level yesterday, next day as well.
It’s like Save function of role-playing games, you know.
By recording diary, as well as diet and workout,
you can keep motivation like
“I did so much yesterday, so it’s a waste if I don’t do it today as well!” ,
and you must be able to keep practice fun.
