A standard piano has 88 keys – 52 are white, 36 are black. The white keys represent standard notes whilst the black keys represent the sharps in between each standard note.
Similarly, Crystal Singing Bowls are also tuned to the same musical notes. Our 'Standard' bowls play the standard notes (i.e. white keys on the piano), while the 'Sharp' bowls play the sharp notes (i.e. black keys on the piano).
From the Base/Root bowl (C note), if you play the next 7 bowls (Soul Star C5 note), you’ll be playing the ‘full octave’ Do-Re-Mi-Fa-Sol-La-Ti-Do
