The Harmonic Table keyboard layout was used in a keyboard harmonica called the Harmonetta, [2] invented by Ernst Zacharias [3] and manufactured by Hohner from the early 1950s through the mid-1970s. A similar keyboard was developed by Larry Hanson [ 4 ] in 1942 for use with a 53 tone scale but turns the fifth sideways and the major third to the ...
Harmonic flat Lowers the pitch of a note to a pitch matching the indicated number in the harmonic series of the root (bottom) of the chord. The diagram shows a specific example, the septimal flat , in the context of a septimal minor third , in which the E ♭ is tuned exactly to a 7:6 frequency ratio with the root (C).
The concept of harmonic function originates in theories about just intonation.It was realized that three perfect major triads, distant from each other by a perfect fifth, produced the seven degrees of the major scale in one of the possible forms of just intonation: for instance, the triads F–A–C, C–E–G and G–B–D (subdominant, tonic, and dominant respectively) produce the seven ...

Harmonic analysis is a branch of mathematics concerned with investigating the connections between a function and its representation in frequency.The frequency representation is found by using the Fourier transform for functions on unbounded domains such as the full real line or by Fourier series for functions on bounded domains, especially periodic functions on finite intervals.
For example, the greater just minor seventh, 9:5 (Play ⓘ) is a 5-limit ratio, the harmonic seventh has the ratio 7:4 and is thus a septimal interval. Similarly, the septimal chromatic semitone, 21:20, is a septimal interval as 21÷7=3. The harmonic seventh is used in the barbershop seventh chord and music.
QUITO (Reuters) - The IMF on Thursday said its executive board completed the first review of an extended fund facility for Ecuador, allowing for an immediate disbursement of around $500 million.
Undertone series on C. [1] In music, the undertone series or subharmonic series is a sequence of notes that results from inverting the intervals of the overtone series.While overtones naturally occur with the physical production of music on instruments, undertones must be produced in unusual ways.
