"Coqui Frog" is an Aeolian chord progression in the key of C, resolving to the VI minor chord (Ami7) making it an A Aeolian progression. In this track, I've added in the sus to the minor chord to add some movement.
This is a great groove to jam over and a nice progression to build some layers. The chords used are Ami7 - Ami7sus - Dmi7 - C/D - G making this a VI - VIsus - II - I - V progression in Roman numerals. Try transposing this progression into another key based on the scale degree formula I've given you. Solos would sound great using the A Aeolian mode (C major scale) or even the A minor pentatonic, D minor pentatonic, etc.
