What actually happens when you open Tomus
No trailer, no promises about rewiring your brain. Here is the structure of the app and what a session looks like.
A session, start to finish
You pick a game, or take the Daily Jam
The Daily Jam is a prepared set that mixes exercises across skill areas. Otherwise you choose a specific game from the grid — rhythm tap, find all the notes, identification of pitches, and others.
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.
Each answer is corrected immediately
You are shown the correct answer, with reference information where it is useful. Wrong answers are the point of the exercise, not a failure state.
The run ends with a summary
Correct, incorrect, accuracy and elapsed time. Progress is tracked across the five areas, so a persistent weak spot becomes visible rather than vague.

The five areas
Music theory
Intervals, scales, chords, key signatures. Recognition questions rather than written exercises.
Read the theory →Sight-reading
Naming notes on the staff, finding notes in a sequence, reading rhythms against a time signature.
Read the theory →Ear training
A pitch or passage plays; you identify what you heard. Randomised, with immediate correction.
Read the theory →Rhythm
Tapping patterns back against a pulse, and matching rhythms to time signatures.
Read the theory →Music outlook
Instruments, recordings and composers, from the medieval period through to the romantic.

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.
