Some exercises are even extracts from famous music. - Simply Read Notes offers two training modes to suit all levels: o Smart mode: let yourself be guided with our complete learning program available in four different clefs (bass clef, treble clef, alto clef and tenor clef).

So move forward at your own pace. o Manual mode: à la carte learning with three types of exercises (with key, without key and visual interval recognition). In this mode, everything is configurable: § Stopwatch § Survival mode § Selection of notes for exercises with clef § Choice of difficulty level § Playing mode (static notes, moving notes, notes to be found after being hidden) § Choice of the number of correct answers § Display of reference notes (with reference to the Dandelot method) Manual mode is ideal for targeting a particular difficulty. Also discover our daily challenges. A new exercise is offered to you every day. The application does not contain advertising and is free. You have a limited number of energies, which are renewed gradually and you have the possibility of purchasing energies. Notes available in three languages ​​(Do ré mi fa sol la si do, C D E F G A B, C D E F G A H). Simply Read Notes is a real “Swiss army knife” for reading notes and will help you make significant progress in music theory. If you are starting to learn music and want to practice progressively and tailor-made, this application is for you!
