  2. Five-limit tuning - Wikipedia

    en.wikipedia.org/wiki/Five-limit_tuning

    5-limit Tonnetz. Five-limit tuning, 5-limit tuning, or 5-prime-limit tuning (not to be confused with 5-odd-limit tuning), is any system for tuning a musical instrument that obtains the frequency of each note by multiplying the frequency of a given reference note (the base note) by products of integer powers of 2, 3, or 5 (prime numbers limited to 5 or lower), such as 2 −3 ·3 1 ·5 1 = 15/8.

  3. Harmonic series (music) - Wikipedia

    en.wikipedia.org/wiki/Harmonic_series_(music)

    For example, a perfect fifth, say 200 and 300 Hz (cycles per second), causes a listener to perceive a combination tone of 100 Hz (the difference between 300 Hz and 200 Hz); that is, an octave below the lower (actual sounding) note. This 100 Hz first-order combination tone then interacts with both notes of the interval to produce second-order ...

    Section 8.1 of the Texas Instruments NE555 datasheet [1] states a value of 100 kHz, and their website shows a value of 100 kHz in timer comparison tables. Signetics App Note 170 states that most devices will oscillate up to 1 MHz; however, when considering temperature stability, it should be limited to about 500 kHz. [ 2 ]

  5. Interval (music) - Wikipedia

    en.wikipedia.org/wiki/Interval_(music)

    The size of an interval between two notes may be measured by the ratio of their frequencies.When a musical instrument is tuned using a just intonation tuning system, the size of the main intervals can be expressed by small-integer ratios, such as 1:1 (), 2:1 (), 5:3 (major sixth), 3:2 (perfect fifth), 4:3 (perfect fourth), 5:4 (major third), 6:5 (minor third).

  8. Subminor and supermajor - Wikipedia

    en.wikipedia.org/wiki/Subminor_and_supermajor

    A supermajor second (or supersecond [2]) is intermediate to a major second and an augmented second. An example of such an interval is the ratio 8:7, or 231.17 cents, [1] also known as the septimal whole tone (D-Play ⓘ) and the inverse of the subminor seventh. Another example is the ratio 15:13, or 247.74 cents (D ♯).
