Keys that mix with G major

On the Camelot wheel G major is 9B (Open Key 2d). Tracks in these keys mix without a clash:

• 9A E minor relative minor, the same seven notes
• 8B C major one step down
• 10B D major one step up
• 11B A major two steps up, the energy boost

Same keynote, the other mode: G minor (6A), three notes apart.

Where G major sits

Choir parts (soprano C4–G5, alto G3–D5, tenor C3–G4, bass F2–D4, where two part-writing guides agree): G4–G5 fits the soprano part; G3–G4 fits the alto and tenor parts; G2–G3 fits the bass part. Find your own range.

As a sub or an 808, the keynote is G1 at 49.0 Hz, or G2 at 98.0 Hz an octave up. Tune an 808 to G.

What plays

Drums, an organ bass and a pluck, the Brumm app's own sounds, four bars at 123 BPM, one chord per bar. The arrows move bass and chords a semitone; the drums stay.

Then hum over it

The hum button opens Brumm with a short line in the key over a beat. Hum yours and it becomes an instrument. No account, no upload.
