this is me playing the bass part of the song which is played by the left hand. these chords are composed of the chords i learnt in class. the chords are as follows: major chords, minor chords, major 7 chords, minor 7 chords, dominant 7 chords, 9 chords and more. in fact, those are the typical jazz chords so i need to be able to memorize how to play it so it would make my life easier in the future when having to learn a new jazz song
