Tomus

What actually happens when you open Tomus

No trailer, no promises about rewiring your brain. Here is the structure of the app, game by game.

A session, start to finish

  1. You answer a few questions before you start

    The first run asks which of the five areas you care about and gives you a short test in each. That sets your starting level rather than dropping everyone at the beginning.

  2. You take the Daily Jam, or pick a game

    The Daily Jam is a prepared set for that day, drawn from ear training, sight-reading and rhythm. Otherwise you choose from the game grid.

  3. You answer around ten questions

    A timer runs and you have a small number of lives. Questions are multiple choice, tap-to-match, or listen-and-identify depending on the game.

  4. Each answer is corrected immediately

    You are shown the correct answer, and written questions carry an explanation. You can review the whole run afterwards, question by question.

  5. The run ends with a summary

    Correct, incorrect, accuracy and elapsed time, plus your progress across the five areas and your daily streak.

The 26 games

Five areas. The reading, listening and rhythm games generate their questions, so they do not run out; the theory and outlook games draw on a bank of about 2,441 written questions, each with an explanation attached.

Sight reading

Generated exercises

Notes on the stave, named against a timer. Treble clef to begin with; bass clef arrives as you progress, and the range widens with it.

Music outlook

From the question bank

The context around the notation: who wrote what, which instrument is which, and where a piece sits in history. This is where most of the curated question bank lives.

  • Composers
  • Instruments
  • Music history
  • Music genre
  • Music records
  • Music Faces
  • Classical compositions
  • Christmas carolsSeasonal in subject, but listed all year.

A Christmas carols game also appears seasonally.

Progression is not decoration

There are 10 levels, from Novice to Legend, and they change what you are shown rather than just awarding a badge.

  • Reading games start in treble clef only. Bass clef arrives a few levels in, once the treble notes are reliable.
  • The range of notes widens level by level, starting from a single octave.
  • Several games are locked until you reach the level they are written for.

What you get without paying

The app is free to download, and 3 of the day’s 5 Daily Jam exercises are playable without a subscription, every day. A premium subscription unlocks the remaining two and the rest of the library.

That is enough for a daily habit without paying anything. See the FAQ for current prices.

What Tomus does not do

  • It does not teach you to play an instrument, and it does not listen to you play one.
  • It is not a course. There is no syllabus that ends with a certificate.
  • It does not teach concepts from scratch — that is what the free Learn section on this site is for.
  • There is no Android or web version.
