What are the notes on a 29 key keyboard?

A 29-key keyboard typically spans nearly two octaves and includes the notes from C to C, covering the range of C3 to B4. The keys consist of both white and black keys, representing the natural notes (C, D, E, F, G, A, B) and the sharps/flats (C#, D#, F#, G#, A#). The specific layout may vary, but the standard pattern of whole and half steps remains consistent across keyboards. This setup allows for a variety of musical expressions, even within a limited range.
