Clarinet (B♭) Note Reading Practice
The B♭ clarinet is a transposing instrument: when a clarinettist reads a written C, the sound that comes out is B♭. That makes the written part two semitones (a major second) higher than concert pitch. This tool does the transposition for you, so the sound you hear and the pitch the microphone listens for are the real, sounding notes.
What to know about reading for clarinet
Clef: Treble clef (transposing). Pitch: B♭ clarinet sounds a major second (two semitones) lower than written.
- Written pitch is a major second above the sounding pitch.
- Written C sounds B♭.
- Written lowest note: E3, sounding D3.
- Key signatures in written parts have two extra sharps (or two fewer flats) compared with concert pitch.
Practice tips
- Learn the break (the join between the low and high registers) as a landmark.
- Read in written pitch and let the instrument handle the transposition.
- Use mic mode to check that your written note matches the app.
- Practise key signatures slowly: a piece in C written for clarinet sounds in B♭.
Where the notes sit
See the full chart for your clef: treble clef notes, bass clef notes or alto clef notes. Add key signatures once the stave feels easy.
Frequently asked questions
Why is the clarinet a transposing instrument?
The B♭ clarinet is built so that its fingerings match those of other clarinets in the family. Music is written in a key that suits the player and transposed on paper.
If I play a written C, what does the piano play?
A piano playing the same sound plays B♭.
Does the app listen for the written or the sounding note?
The sounding note. Play the written note on your clarinet and the app expects the transposed pitch.
What about A clarinet or E♭ clarinet?
