In music theory, limits or harmonic limits are a way of characterizing the harmony found in a piece or genre of music, or the harmonies that can be made using a particular scale. The term limit was introduced by Harry Partch , [ 1 ] who used it to give an upper bound on the complexity of harmony; hence the name.
For 12 tone equally-tempered tuning, the fifths have to be tempered by considerably less than a 1 / 4 comma (very close to a 1 / 11 syntonic comma, or a 1 / 12 Pythagorean comma), since they must form a perfect cycle, with no gap at the end, whereas 1 / 4 comma meantone tuning, as mentioned above, has a residual ...
According to John Fogerty, he began working on "Keep On Chooglin'" (as well as "Born on the Bayou" and "Proud Mary," which also appeared on Bayou Country) during his time in the US Army Reserves. [1] He continued working on those songs after his discharge and throughout most of 1968, during which time he came up with the idea to cross-reference ...
In these limits, the infinitesimal change is often denoted or .If () is differentiable at , (+) = ′ ().This is the definition of the derivative.All differentiation rules can also be reframed as rules involving limits.
Assume heat transfer [2] is occurring in a heat exchanger along an axis z, from generic coordinate A to B, between two fluids, identified as 1 and 2, whose temperatures along z are T 1 (z) and T 2 (z). The local exchanged heat flux at z is proportional to the temperature difference:

The first four partial sums of the series 1 + 2 + 3 + 4 + ⋯.The parabola is their smoothed asymptote; its y-intercept is −1/12. [1]The infinite series whose terms ...
Thus, for example, 50:49 is a 7-limit interval, but 14:11 is not. 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.
