One flat: B♭; one black key on a piano (B♭). Whole and half steps: W H W W H W W.

Harmonic minor raises the seventh to C♯: the chord on the fifth degree turns major (A, A7) and pulls back to D.

Keys that mix with D minor

On the Camelot wheel D minor is 7A (Open Key 12m). Tracks in these keys mix without a clash:

• 7B F major relative major, the same seven notes
• 6A G minor one step down
• 8A A minor one step up
• 9A E minor two steps up, the energy boost

Same keynote, the other mode: D major (10B), three notes apart.

Where D minor sits

Choir parts (soprano C4–G5, alto G3–D5, tenor C3–G4, bass F2–D4, where two part-writing guides agree): D4–D5 fits the soprano and alto parts; D3–D4 fits the tenor and bass parts. Find your own range.

As a sub or an 808, the keynote is D1 at 36.7 Hz, or D2 at 73.4 Hz an octave up. Tune an 808 to D.

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.
