Bemol review
A focused macOS trainer for tonal relative-pitch practice, without interval, chord, or rhythm drills.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Bemol is a free, open-source ear-training application for music hobbyists and students who want to develop relative-pitch recognition within tonal contexts. It establishes a key with an I–IV–V–I cadence, then presents played-note identification exercises and short melodic resolutions to the nearest tonic. Practice begins with notes in C major and expands through progressive levels based on accuracy, making the application suited to learners who prefer a focused, note-centered path rather than a broad collection of ear-training drills.
Its main strength is the depth of its tonal relative-pitch approach. Once scale practice is established, Bemol adds chromatic-note exercises and supports practice across 12 major and 12 minor keys. A random-key practice mode becomes available after initial key mastery, extending practice beyond a single familiar tonal center. This progression gives the product a clear learning structure while keeping the core exercise centered on hearing notes in relation to a key.
The trade-off is narrow coverage. Bemol does not provide interval, chord, or rhythm exercises, and it is distributed only as a native macOS application. That makes it a good choice for macOS users seeking free, open-source practice focused on tonal note recognition and relative pitch. Learners who need a broader ear-training curriculum, mobile access, or dedicated work on intervals, chords, or rhythm should choose a different tool.
