To do this tutorial you need to know what a tone is.
A minor 7th is a tone less than an octave.
- So C-Bb is a minor 7th because Bb is a tone down from C,
- and Eb-Db is a minor 7th because Db is a tone down from Eb.
Minor 7ths are often just called
7ths because they’re so much more common than major 7ths, so if you hear someone saying
a 7th they probably mean
a minor 7th.
Test yourself on 7ths, focusing on the ones you find hardest. For most people they’ll be the ones on Db and F#.
