OK you have to start playing small pieces of musical information through all 12 keys every day. It will make you smarter.
There are 12 musical notes. Just like there are 12 months and 12 hours on a clock. You must decentralize, and love them all equally.
Playing things in 12 keys every day is like investing regularly in crypto or the stock market you just HAVE TO START. There is never the right time. Don't wait. Start today.
Generate a 12 tone matrix here https://www.musictheory.net/calculators/matrix
(or I attached one at the bottom)
Play all 12 notes from left to right with a metronome. https://www.metronomeonline.com/
Start small. Slow. 60bpm or slower. Just individual notes. Hold each note for 4 to 8 beats. Make it a meditation. You want to love Db (Dee Flat) on your instrument as much as you love C. Move to tempo up a bit. Play it PERFECTLY! Move the tempo up a bit more.
Once you can play all your notes randomly and perfectly move to intervals. (If you get bored or stuck, or don't understand this skip it and come back)
minor 2nd. Major 2nd. Minor 3rd. Major 3rd. Perfect 4th. Tritone. Perfect 5th. Minor 6th. Major 6th. Minor 7th. Major 7th. Octave.
Go back and forth between the two notes in an interval in find the natural music in each distance.
TRIADS??? TRIADS!!! TRIADS... If you can play your MAJOR, AUGMENTED, MINOR, and DIMISHED triads through all 12 keys with a metronome at a reasonable tempo there is nothing stopping you from becoming a professional musician as long as you are groovy.
Play them slowly. Root position first. Then 2nd inversion. Then 1st inversion. Then closest inversion.
Digital Patterns!
Then move digital patterns through all 12 keys. 1 2 5 7 ex C D G B or F# G# C# F or Eb F Bb D
1 5 b3 m7 ex C G Eb Bb or F# C# A E or Eb Bb Gb Db
Play melodies in all 12 keys. The theme from Rhapsody in Blue, Bag's Groove, Eine Kleine Nachtmusic. Whatever your ALL TIME FAVORITE STUFF IS play it in all 12 keys.
Symmetrical stuff to put through all 12 keys
Chromatic Scale( C C# D D# E F F# G G# A A# B) Whole-Tone Scale ( C D E F# G# A#) and ( Eb F G A B Db)
Diminished 7 Chord (C Eb F# A) (C# E G Bb) (D F Ab B) Augmented Triad. ( C E G#) (C# F A) (D F# Bb)
1 4 m7 (4ths) ex C F Bb or F# B E
1 5 9 (5ths) ex C G D or F# C# G#
Get at me if you have questions.
Here is a random roots sheet I grabbed from antonjazz.com
I like the Metronomics app too
