CadenzaF minor thirteenth
Fm13
Also written Fmin13 · F−13
The minor 13th — the complete dorian sound. The 13th (D) is a major 6th, and it is what makes the chord dorian rather than natural minor.
How pianists voice Fm13
Nobody plays a jazz chord in root position. These are the shapes that actually get played — the same ones Cadenza shows when you play the chord.
Shell Left hand
1 · ♭3 · ♭7 — root, 3rd and 7th: the three notes that say what the chord is. Left hand, low; everything else is colour.
Rootless A From the 3rd
♭3 · 13 · ♭7 · 9 — no root: the bass player has it. The left-hand voicing of modern jazz piano.
Rootless B From the 7th
♭7 · 9 · ♭3 · 13 — the other half of the pair. A and B alternate through a ii–V–I so the hand barely moves.
Drop 2 Two hands
13 · 1 · ♭3 · ♭7 — close position with the second voice from the top dropped an octave: wider, warmer, the standard for chord melody.
