# Earstep

> Earstep is a daily ear-training app for iPhone and Android. It plays a sound on a sampled grand piano and you name it: intervals (rising, falling and together), chords (triads, inversions, seventh chords), scales and modes, and notes, either against a named reference note or with no reference at all. After each answer the sound is drawn as a harmonograph figure of its frequency ratio. 56 levels in 10 tracks, 14 of them free; the optional Earstep Pro is $39.99 a year after a 7-day free trial, or $79.99 once. No account is needed, and it never uses the microphone.

## What it trains
- Rising intervals (7 levels): Two notes, the second higher.
- Falling intervals (7 levels): Two notes, the second lower.
- Intervals together (7 levels): Two notes at once.
- Triads (4 levels): Major, minor, augmented, diminished and suspended.
- Inversions (4 levels): Which note of the chord is in the bass.
- Seventh chords (5 levels): The six common seventh chords.
- Scales (5 levels): Major, the three minors, pentatonics, blues and more.
- Modes (5 levels): The seven modes of the major scale.
- Notes from a reference (6 levels): Hear a named note, then name the next one.
- Perfect pitch (6 levels): Name a note with no reference at all. It trains naming notes without a reference; it does not promise perfect pitch.

## How it schedules practice
- Each sound has a Leitner box. A right answer moves it up at most one box a day; it then comes back after 1, 3, 7, 14 and 30 days. A miss moves it down a box and brings it back within 10 minutes.
- A sound counts as mastered once it has been right on 3 separate days. A level passes at 75 to 85 percent, depending on how many answers it has.

## The sound
- Every clip (1,309) is rendered from Salamander Grand Piano by Alexander Holm (Creative Commons Attribution 3.0 Unported (CC BY 3.0)), retuned to equal temperament at A4 = 440 Hz (every note within 0.8 cents) and matched in loudness at -19 LUFS (within 0.73 LU).
