How to use the tuner
Bowed strings, woodwinds and brass play continuously until stopped. Plucked strings, keyboards and pitched percussion repeat slowly so that each instrument’s natural attack remains audible.
Notes can be selected chromatically from C1 to C5. International notation uses B for the note called H in Czech.
