Tonaly Tune

Knows your instrument, so you don't have to yet

Most tuners show you a needle and assume you know the rest. Tune picks up where that leaves off: choose your instrument and it walks each string, telling you which way to turn.

Features

Built for the first year, not the tenth

  • Guided, string by string

    Pick your instrument and it walks the strings in order, naming each one and telling you which way to turn.

  • Knows twelve instruments

    Violin, viola, cello and double bass; guitar and ukulele; flute, clarinet, oboe, bassoon and saxophone.

  • Handles transposing instruments

    A clarinet's written C sounds a B flat. Tune shows the note you read, and measures the pitch you sound.

  • Accurate on low notes

    A cello's low C and a bass low E defeat many tuners. Tune detects the pitch, not the loudest harmonic.

  • Hear the target

    Tap to sound the note you are tuning to, for when your ear is a better guide than your eyes.

  • Any reference pitch

    440 by default, 442 for orchestras that tune sharp, 415 for baroque — or anything in between.

In practice

For the things a tuner usually assumes you know

You don't know which string is which

Tune names them and works through them in order, with a note on where each sits on the instrument. Play, and it tells you whether to tighten or loosen.

A string is badly out

A string tuned nearly a semitone flat reads as a different note entirely on a chromatic tuner. Tune measures against the string you're aiming for, so it says you're flat of G rather than showing you an F sharp.

Tuning to other players

Set the reference pitch to match the ensemble — 442 is common, and picking the oboe sets it for you.

You'd rather tune by ear

Tap the speaker to sound the target note and match it. The meter is still there when you want to check.
