To do this tutorial you need to know what a tone is.
Two notes are a major 3rd apart if they’re 2 tones apart.
- So C-E is a major 3rd because C-D is a tone and D-E is a tone,
- and D-F# is a major 3rd because D-E is a tone and E-F# is a tone.
Test yourself on major 3rds, remembering to include some that start on black notes.
