38.75“Happy Birthday” transformation

This is a particularly fun one.

Put the melody into an F-minor/funk environment.

Keep it recognizable.

Intro

one-bar bass vamp repeated.

Phrase 1

melody mostly alone over vamp.

Phrase 2

add short syncopated RH stabs.

Phrase 3

higher register + blues/Dorian fills.

Final phrase

rhythmic stop.

Ending

one repeated riff → final Fm6/9-type chord.

You changed almost none of the melodic identity.

Yet the piece has been completely reimagined.
