PIANO SONG BUILDER
Rocmaestro Music Ideas
Three chords. Any key. Your song.
Learn the I–IV–V chord family, hear each chord, try inversions and bass patterns, then arrange an 8-bar song in Gospel, R&B, Pop, or Blues style.

Why these three chords work
I / i — Home
Your musical resting place.
IV / iv — Movement
Moves the song forward.
V — Tension
Creates a pull back toward home.
Rocmaestro tip: Start simple. Once the progression feels good, hum a melody over it. That's where the song begins.
