Pitch 1024
12 notes · 5 musicians · by Chardonn.AI

Find your pitch — in a musician's voice.

A pocket pitch pipe — reference notes, starting pitches for any key, harmony, and ear-training. Every note is a real musician singing, not a tuner's beep: match your pitch to a voice worth matching.

The same instrument, two ways to reach it:

The musicians

A beep gives you the frequency. A fine voice gives you the sound to reach for.

Five accomplished musicians lent their voices to Pitch 1024 — every note is a real performance, recorded, not synthesized.

LéaSopranoclear, high
Blue JayAltobright mid-high
SoulmanTenor · Descant (falsetto)soulful mid, with a soaring falsetto top
Harry KimBaritonewarm low-mid
Deep BassBassthe foundation — lowest, rich

What it can do

Give a pitch
A reference note — or a few — in the musician's voice you choose. Tuning, a starting note, a melody to match.
Voices in harmony
Several vocalists each take a note of a chord and sound them together — in stereo, or in full 3D around you (headphones).
Starting notes
Hand a singer or an a cappella group their starting pitches for any key — SATB-aware.
Sing a progression
A chord progression, sung steadily and looping — each chord can even have its own vocalist.
Train your ear
Name-the-note, interval, and chord-quality drills — the answer stays hidden until you guess, then your chat grades you and coaches your next step.

Try saying…

Sing a chordHave a Cmaj7 sung together — Deep Bass on C, Soulman on E, Blue Jay on G, Léa on B.
Surround me (3D)I've got headphones on — have the voices sing a Cmaj7 all around me, slowly orbiting.
Starting notesWe're singing in F major — give our SATB quartet their starting notes.
Quiz my earDrill me on intervals with Harry Kim — keep it hidden until I guess, and track my streak.
