Common Tones
Common tones are the notes that two scales or modes share. Knowing which notes the B♭ mode shares with its parallel modes (same root, different scale) helps with improvisation, modal interchange, and smooth voice leading. The more notes two modes share, the more closely related they sound — and the easier it is to slide between them in a solo or progression.
