This is a Chord-Melody Solo with LOTS of chord changes...
It features a type of 'chord-movement' I call voice-leading...where one note in a chord continually moves, causing the 'name' and 'function' of the chord to continually change.
This effect, 'voice-leading' is very pleasing to the ear.
It is subtle harmony and a mechanism used by many musicians and song writers to evoke positive and happy emotions in the listener.
At any rate, a fairly simple, yet challenging arrangement.
At the very least, fun to listen to when Tabledit is doing the performance!
