Create a tuning from semitone intervals

Enter the tonic, using 'b' for flat and '#' for sharp, and a series of intervals separated by commas and/or spaces. Intervals may be 'T' for a full tone or 'S' for a semitone, and multiples may be indicated with a number (e.g., '3S' for three semitones)

Example: Hucbald's hexachord has tonic C and intervals T T S T T.
