Groovy Jazzy

This is a moderate jazz feel alternating between two seventh chords that are one step apart.

Alternating chords that are as close together as this (one whole step) can be tricky since the key centers are not as close. Think of Bb7 as three flats (key of Eb major) and the Ab7 as five flats (key of Db major). 

Keep in mind that seventh chords like these can sound interesting if you raise the 11. The best example here is to play D natural, which is the third of the Bb7 and the sharp 11 of Ab7. Play that note and the other common tones to hear how they sound.
