"E-Sharp and B-Sharp" and the Double FlatWhat is the meaning of the sharps on the E and B line, and of a double-flat? Are they merely theoretical?They are not theoretical, but orthographical. You confound the note Cwith the key on the keyboard by that name. B-sharp is played upon the key called C, but its musical bearing is very remote from the note C. The same applies to double-flats (and double-sharps), for D with a double-flat is played upon the key called C, but it has no relation to the note C. This corresponds precisely with the homonym in language: "sow"—"sew"—"so"—sound alike, but are spelled in various ways according to the meaning they are to convey.
