A tuner that listens like a musician
Clarity where other tuners lose the note.
Fine Tuna separates a stable musical pitch from the noise, overtones, and changing envelope around it. That makes the display unusually readable on instruments that are difficult to hear electronically.
01
Respond quickly, without chasing the attack
Fine Tuna finds the stable musical pitch through fast attacks, noise, overtones, and changing envelopes—even on difficult instruments.
02
Make the display yours
Strobe shape, colors, opacity, geometry, harmonic lanes, pitch washes, and light or dark appearance are all customizable.
03
Keep the musical context
Temperament, transposition, accidentals, reference pitch, and display choice stay connected while you tune.
Customize the display
See pitch the way you want.
Move from a calm frame to a precise ring strobe, a pitch bar, harmonic analysis, or recorded review. Fine Tuna’s views share one tuning engine, so changing the picture never changes the musical answer. Some examples of the available views:
Frame + Strobe
Read direction and distance at a glance, then use the motion to settle precisely.
Ring Strobe + Wash
A focused circular strobe with an ambient color field for peripheral feedback.
Harmonic Strobe
See the note and its upper partials together, especially useful for complex tones or tuning 4′ organ pipes.
Tuner Gallery
Browse the display families and choose the view that suits the instrument in front of you.
Built for iPad too
More room for the tuning picture.
On iPad, Fine Tuna opens into a broader workspace. The tuner, keyboard, temperament library, and settings stay within reach while the display gets room to breathe.
Make it yours
Every useful detail is adjustable.
Choose stripe, ring, or wave strobes, a pitch bar, or a precision band that zooms in on just 5 cents around the target. Move the readout; adjust colors, opacity, geometry, and harmonic lanes; and choose and light or dark appearance. Save your own displays and sync them through iCloud to all your devices.

Temperament Explorer
Understand the tuning before you play it.
Choose from 40 built-in temperaments—or define your own. Study a temperament by itself or compare it with another. Inspect fifths, step sizes, ratios, deviations, and pitch spellings. Listen to chord progressions in any temperament and see how its character changes in every key.

Notation that follows the music
Read pitch in the language you use.
Choose note names and octave conventions independently. Fine Tuna carries that choice through the tuner, keyboard, temperament tools, and passage review.

A keyboard built for listening
Hold the reference. Hear the difference.
Fine Tuna’s keyboard uses the same active temperament, reference pitch, transposition, and accidentals as the tuner. It can be a pitch source, a chord partner, or a laboratory.
Just Intonation Mode
Pick a reference pitch and tune notes pure against it. Experiment with “barbershop” dominant sevenths or adjust each locked note’s volume.
Temperament Compare Mode
Choose two temperaments and flip the keyboard between them to hear differences immediately.
Messa di voce
Practice against sustained chords with individual notes swelling and fading.
Sampled or synthesized
Choose among pure waveforms, synthesized instruments, or sampled flute, clarinet, trumpet, or organ sounds.
Stretch Tuning
See the curve behind the tuning.
For instruments whose inharmonic partials make pure octaves sound wrong, Fine Tuna can calculate a stretch-tuning curve based on the specific instrument. Choose among several stretch curves—clean 4:2 octaves, 8:2 double octaves, or more advanced algorithms like Minimum Entropy, based on work by Haye Hinrichsen. Record your own instrument to create a customized curve based on its own spectrum.

After the note is over
Review the phrase, not only the instant.
Live feedback is just one way to listen. Record a passage and Fine Tuna maps its intonation over time: a timeline of every note, a per-note report, and a pitch map—with playback at full or half speed, note by note.
History & Pitch SpectrogramFollow pitch movement, strength, and continuity as it unfolds.

The musician behind Fine Tuna
Built by someone who tunes every day.
Hi, I'm Jeffrey Grossman, a harpsichordist and conductor, and the man behind Fine Tuna. I tune my instrument every day, and as an early music nerd, I care a lot about temperaments and pitch systems! I want to give musicians the tools to decide for themselves what “in tune” means, and to understand what their choice of temperament does to the music. Happy tuning!
