Before you play a chord, say the name of the chord out loud... then get to the chord as quickly as you can. I used this method to greatly improve my reaction times and it helped me eventually remember all the chords I knew off by heart.
The brain processes this information then sends a signal through motor neurons down the arm to tell the
muscles in the hand to close and play the chord. The amount of
time this all takes is what makes up our
reaction time. ... This is often referred to as
muscle memory.
If you like you can also use this
RANDOM PICKER wheel and test your reaction times this way.
Choose 1 chord at a time OR pick 4 or more chords together and try to play them in a sequence.
Goal: To combine your muscle memory with your reaction time. Say a chord at random, then play it simultaneously (or as quickly as possible)
