Musical scale The frequencies 440Hz and 880Hz both correspond to the musical note A, but one octave apart. The next higher A in the musical scale would have the frequency 1760Hz, twice 880Hz. In the western musical scale, there are 12 notes in every octave. Left is a table of the complete musical scale between middle A and A-880. The psychoacoustic properties of the musical scale are fascinating. Frequencies that are harmonically related tend to sound good together. The blue waveform is the sound you hear, which is a combination of the other (pure tone) waveforms. What about 440 × 3 = 1320? For somewhat more arcane reasons, the interval between A and E, which is a frequency rise of 3/2, is called a fifth. Where does the C sharp come from in the major triad? Among all the harmonic relationships in the scale, A, C sharp, and E have among the simplest. A major triad can be written as a sum of sinusoids s(t) = sin(440× 2π t) + sin(554 × 2π t) + sin(659× 2π t). The human ear hears frequencies.
