## Description

Compare temperaments by ear and eye. Explore fifths, intervals, chords, key quality, and pitch offsets—then tune with the system you choose.

Fine Tuna is a precision tuner for professional musicians—especially early music specialists who need to understand exactly what a temperament is doing.

Created by professional harpsichordist and conductor Jeffrey Grossman, Fine Tuna lets you compare temperaments visually, numerically, and by ear. Start tuning instantly in Simple mode, with advanced tools always just a tap away.

TEMPERAMENTS AND TEMPERAMENT EXPLORER

- Set A anywhere from 300–600 Hz in 0.1 Hz increments—or play the A you need
- Explore 40 built-in temperaments, with historical background and facsimile sources
- Create custom temperaments using cents offsets or fractions of a syntonic or Pythagorean comma, automatically synced to your other devices
- Transpose temperaments up or down
- Support split enharmonics such as C#/Db and D#/Eb, including listening and playing
- Convert instantly between cents offsets and the circle of fifths
- Use the Temperament Explorer to see and hear a temperament’s circle of fifths, interval sizes, major and minor triads, key character, modulation paths, and harmonic progressions
- Compare two temperaments directly in the Explorer
- Save temperament and pitch presets for quick recall

ADVANCED KEYBOARD

- Choose from 13 sounds, including simple waveforms, synthesized instruments, and sampled flute, clarinet, trumpet, and organ
- Customize key size, keyboard appearance, and starting pitch
- Flip instantly between two temperaments with Temperament Compare
- Use Just Intonation mode to play a chord, lock a reference note, and tune the other notes pure against it
- Explore four different tunings of the dominant seventh chord
- Use the resizable inline keyboard on the tuning screen or switch to the full-screen Keyboard tab

CUSTOMIZABLE TUNER VIEWS

- Choose from Frame, Bar, three types of strobe, additional octave and harmonic displays, and more
- Edit built-in views or create custom copies with your own colors, frame shapes, and strobe settings
- See tuning hints in your selected temperament, such as:
  “Bb → Eb: pure” or “Bb → D: 13.7c wide, 8.7 beats/sec”
- See octave strobe tuners 

PASSAGE REVIEW AND STRETCH TUNING

- Record up to 60 seconds of music and review your performance by pitch
- Play back individual notes—for example, every F you played—to hear how consistent they were
- Play a scale to evaluate your instrument and adjust A4 or the temperament to find the best fit
- Sample your own keyboard instrument to create a custom stretch-tuning profile across the register, synced to your other devices

LOCKED NOTE AND AUDIO OPTIONS

- Lock the tuner to one pitch and ignore other input
- Move manually or automatically by semitone
- Add an optional drone that follows the locked pitch
- Use the built-in microphone while listening through headphones, or connect an external microphone

Fine Tuna turns tuning into something you can see, hear, compare, and investigate—not just a name in a menu.
