Rootless Voicings — B Form in A Major

Bm9 E13 Amaj9
Left hand only — a bass player (or the audio below) supplies the root.

The audio adds each chord's root in the bass — that's the context these rootless shapes are designed to sit in. The MIDI file is exactly the notation.

The notes

ChordNotes (low → high)Formula
Bm9 A – C♯ – D – F♯ ♭7 · 9 · ♭3 · 5
E13 G♯ – C♯ – D – F♯ 3 · 13 · ♭7 · 9
Amaj9 G♯ – B – C♯ – E 7 · 9 · 3 · 5

Why it works

From Bm9 to E13, a single voice does all the work: A3 falls a half step to G♯3 while the other 3 notes hold. That stepwise pivot is the engine of the progression. Into Amaj9, 3 voices settle by step (total motion of just 5 semitones). Smoothness here is measurable, not a metaphor.

A major puts 7 of the 12 notes on black keys, so the hand rides high on the keyboard — many players find these grips easier to grab here, the way Irving Berlin could only play in F♯. The lowest note is G♯3 in the octave below middle C.

Practice tip: play the progression rubato first and listen for the held tones, then put the metronome on 2 and 4 at a slow tempo. When the grab is automatic, move around the circle of fourths — you are coming from E and headed to D. Say the chord symbols out loud as you play; naming and hearing are different skills, and you want both.

Where A major lives in the repertoire

A major belongs more to guitars than to the songbook, which makes it a stealth weakness for pianists: it appears mid-tune (the bridge of many rhythm-changes contrafacts touches it) and at jam sessions led by singers who count off "same tune, up a half step". The grip is friendly — two sharps under the hand — the surprise is only ever the unfamiliarity.
