An alternative to the solfege
system of sight-singing
, this system
numbers the diatonic scale
with the numbers 1 through 8 (or, alternately, 1 to 7, with the octave
being 1 again.
In this system, 1 is always the root
, but the scale being represented may be major
, or any of the diatonic modes
outside the key signature
) are noted with a + or -
when the numbers are written, but are often skipped when they are spoken or sung.
For example, I might sing "one, three, five, three, one" for a major triad
, but a diminished triad
might be either "one, three, five, three one" or "one, flat three, flat five, flat three, one", depending on how I was taught, and how much I felt like pronouncing two long syllables for one short note.
