Tone Generator

The Tone Generator produces sustained reference tones you can play or sing against. It lives on the Tuner tab — tap the Piano or Hexagon icons to expand it. The tuner stays active while the Tone Generator plays, so you can hear a reference pitch and see your intonation at the same time.

Interface styles

Piano

The Piano interface shows a traditional scrollable keyboard. Tap any key to play that note. Scroll left or right to reach higher or lower octaves.

Hexagon (Honeycomb)

The Hexagon interface arranges notes in a honeycomb grid — a layout also called a Tonnetz. Notes that are harmonically related sit adjacent to each other:

• Notes a perfect fifth apart are direct neighbors.
• Notes a major third apart are diagonal neighbors.

This makes the Hexagon ideal for exploring intervals and chords. Once you learn the pattern, you can find any interval by reaching the same direction from any note.

Pro Tip

Adjacent hexagons reveal harmonic relationships instantly. Tap a note and its neighbor to hear a perfect fifth. Tap a diagonal to hear a major third.

The Sustain button

Tap the ∞ (Sustain) button to hold notes after you lift your finger. With Sustain on:

• Tapping a note holds it until you tap it again.
• Tapping additional notes adds them to the held sound, letting you build intervals and chords.
• Tapping a held note releases it.

With Sustain off, notes play only while you hold your finger down.

Using the tone generator as a drone

A drone is a sustained reference pitch you play or sing against to develop intonation. Because the Tone Generator and the Tuner share the same screen, you can hold a drone and watch the tuner simultaneously — no switching between tabs.

To set up a drone:

1. Enable Sustain.
2. Tap the root note of the key you are practicing in. The panel expands automatically when a note plays.
3. Play or sing along. The tuner shows your pitch relative to the target note in real time.

Tip

A drone on the tonic is most effective for long-tone intonation work. A drone on the fifth is ideal for string players tuning open strings.

Pro Tip

Set the Tone Generator to Sine Wave for the cleanest drone — its pure tone is easiest to tune against without distraction from overtones.

Using the tone generator for interval practice

1. Enable Sustain.
2. Tap a reference note.
3. Tap a second note to hear the interval.
4. Sing or play the interval yourself to train your ear against the reference.
