17. OctaveOctave a pitch an octave higher than another has [i:24] double its frequencya pitch an octave higher than another has [i:24] double its frequency Example: 440 Hertz * 2 = 880 HertzExample: 440 Hertz * 2 = 880 Hertz a pitch an octave lower has [i:25] half the frequencya pitch an octave lower has [i:25] half the frequency Example: 440 Hertz *.5 = 220 HertzExample: 440 Hertz *.5 = 220 Hertz A AA

18. Harmonic Series [i:26] In any harmonic series, the 2nd harmonic is the octave[i:26] In any harmonic series, the 2nd harmonic is the octave For a harmonic series starting on Middle C with a frequency of 261.6 Hertz, the frequency of the 2nd harmonic (octave) is 261.6 x 2 = 523.2 HertzFor a harmonic series starting on Middle C with a frequency of 261.6 Hertz, the frequency of the 2nd harmonic (octave) is 261.6 x 2 = 523.2 Hertz CC …
