Thanks very much! I actually took the chord progression from the tune ‘Georgia on my mind’ - it’s not exactly the same progression, but Oscar Peterson has a lovely version. I also started in F and modulated to Ab using a ii - V for the repeat of the melody - Oscar’s stays in Ab. I’m playing the bass live! Glad you liked it, my schooling has mainly been in jazz bass :)
Depending on how deep you want to get into it, there’s a great book called ‘The Jazz Theory book’ by Mark Levine which goes into a lot of detail about jazz harmony - contains lots of gems, but it’s quite thick. You can dip in and out though depending on what you find interesting. Nice work yourself! Cheers, T
