Learn About Pitch & Ear Training

Short, plain-language guides to how pitch works — each paired with a free game to train your ear.

A good ear is a trainable skill, not a gift reserved for a lucky few, and these guides are built to grow it. Each one explains a single idea in plain language — from pitch and intervals to how we hear frequency — and points you to a matching daily game so you can hear the effect, not just read about it. Everything here is free; a Personal Pass only adds optional progress tracking, and the education tools let a teacher assign a game with a single link.

Pitch fundamentals

• What is pitch? Pitch vs frequency — How your ear turns a sound's frequency into the sensation of high and low.
• Frequency in music: Hz, A440 & concert pitch — What Hz means, why A440 is the tuning reference, and how frequency maps to pitch.
• What are cents in music? — The fine unit — 100 cents to a semitone — for measuring tiny pitch differences.
• What is an octave? The 2:1 ratio & 12 notes — Why doubling a frequency sounds like the same note, and where the 12 notes come from.
• What is timbre? Same note, different sound — Why the same note on a flute and a violin sounds different at identical pitch.

Intervals & relative pitch

• Musical intervals: semitone counts & names — How intervals are named and counted in semitones, from unison to octave.
• Relative pitch vs perfect pitch — The difference between naming a note alone and hearing the distance between two.
• Can adults learn perfect pitch? — What the research says about training absolute pitch after childhood.

Ear training & discrimination

• Interval ear training: a beginner's guide — A step-by-step routine for learning to recognise intervals by ear.
• Pitch JND: how small a difference can we hear? — The smallest pitch gap a listener can reliably hear, measured in cents.
• Tone memory training: improve your pitch recall — How to hold a pitch in memory and recall it more accurately with practice.
• Pitch drift: why we slide off a held note — Why a held note slowly slides off pitch, and how to steady it.

Teaching pitch & ear training

• Teaching pitch perception: a teacher's handbook: How the ear-training games map to classroom skills, with a game-by-skill matrix and notes on hearing differences.
• Pitch and ear-training lesson plans: Ready-to-teach sessions by age group, from octaves and intervals to cents and intonation, each built around a free classroom game.
• Assessment rubrics for pitch skills: Low-stakes formative rubrics for interval recognition, pitch matching, discrimination and tone memory.

Teaching, practice and research

• Pitch perception research bibliography. The peer-reviewed work behind every claim on this hub, grouped by topic.
• A beginner's four-week pitch plan. A few minutes a day for four weeks, built on spaced and interleaved practice.
• Recording and evaluating your pitch scores. How to keep an honest record, and what a daily number can and cannot tell you.
• Inclusive pitch teaching. Hearing loss, cochlear implants and amusia: designing tasks that include everyone.
• Teaching pitch in primary school. Kodaly and Orff-Schulwerk practice, and what young singers can already do.
• Teaching pitch in secondary school. Aural tests, interval work and assessment that survives scrutiny.
