Hearing a wrong note — and which way

The most useful ear skill you can build now isn't hearing that a note is wrong — it's hearing which way. Too high or too low? Because the fix is different, and it's tiny.

What each one sounds like

Too high — bright, sharp, pinched, tight. It sits on top of the drone and won't settle.
Too low — dull, flat, sagging, heavy. It droops under the note it should be.
In tune — it rings. Against a drone or an open string, it locks in and seems to get louder (that's the resonance from the last lesson).

The correction is a millimetre, not a re-place. Lift-and-drop-again trains you to keep missing. Nudge the finger — in the direction your ear just named — and listen again.

3rd-finger D on the A string against the open D. Land it a hair sharp on purpose — hear it go bright and the ring vanish. Then a hair flat — dull, sagging. Then find the centre, where it rings.

Find the planted note

Play this with a drone on D. On one repeat, land the F♯ deliberately low. Name what you hear — 'flat, dull' — then fix only that note, by a millimetre.

The usual mistake

Hearing "wrong" but not which way, so the correction is a guess — and half the time it goes further out. Name the direction first, out loud if it helps, then move. And don't overshoot: small, small, small.

Try

Take a tune you know cold. Play it, and on purpose land one note flat. Stop. Say "flat". Nudge it up until it rings. Do this with a different note each time — you're training the ear to report, not just to wince.
