Quarter-comma meantone each kind, a perfect fifth of meantone contains four diatonic and three chromatic semitones, and an octave seven diatonic and five chromatic semitones, it follows that: Thus, in Pythagorean tuning, where sequences of just fifths (frequency ratio 3:2) and octaves are used to produce the other intervals, a whole tone is and a major third is An interval of a seventeenth, consisting of sixteen diatonic and twelve chromatic semitones, such as the interval from D to F, can be equivalently obtained using either This large interval of a seventeenth contains staff positions. In Pythagorean tuning, the size of a seventeenth
Octave effect as long as the input signal was strong and then continued generating the same frequency while that input signal faded. Octave pedals can be used in conjunction with fuzz (see octafuzz) and/or distortion. It can be used on guitar to make it sound more aggressive (such as the lead-in solo by Prince on When Doves Cry) or sound like a bass. The song Seven Nation Army by The White Stripes features an octave pedal on electric guitar, simulating the sound of a bass.
