Report a fingering or note issue

Include the exact written note and octave, the spelling you were viewing, and the affected hole, register key, additional key, notation or label. If the diagram and written instructions disagree, describe both.

This chart covers standard Boehm-system B♭ soprano clarinet, written E3–C6. State if your report concerns another system, bass clarinet, extra keywork or a specific passage. Include a source when possible, and say whether it describes a basic or alternate fingering.

Report an audio or print issue

Reference audio

Include the selected written note, browser and device, and whether the sound was absent, cut off, quiet or at an unexpected pitch. The synthetic reference tone uses concert pitch, a whole step below the written pitch on B♭ clarinet; written C4 corresponds to concert B♭3.

Printing

Include the paper size selected on the site and in the browser dialog, scale, orientation, and the affected page or note. The chart is designed for four portrait pages at 100% scale with browser headers and footers off.

You may attach a relevant screenshot in your own email application. The website has no upload form. Remove unrelated personal information before sharing it.
