To do this tutorial you need to know the note names.
Summary
A 5th is either:
- two white notes that have 3 white notes in between (e.g. C-G), or
- two black notes that have 2 black notes in between (e.g. Eb-Bb),
with the exception of B-F# and Bb-F.
To do
Practice playing 5ths on the piano, remembering to include some that start on B or Bb.
Sign up to my Piano Chords course to learn how to use 5ths in context.
