The Harmonic Table note-layout, or tonal array, is a key layout for musical instruments that offers interesting advantages over the traditional keyboard layout. Its symmetrical, hexagonal pattern of interval sequences places the notes of the major and minor triads together.
In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized.
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.
Sympathetic resonance or sympathetic vibration is a harmonic phenomenon wherein a passive string or vibratory body responds to external vibrations to which it has a harmonic likeness. [1] The classic example is demonstrated with two similarly-tuned tuning forks. When one fork is struck and held near the other, vibrations are induced in the ...
The metric tensor relative to x is obtained from the metric tensor relative to y by a local calculation having to do with the first derivatives of x ∘ y −1, and hence the Christoffel symbols relative to x are calculated from second derivatives of x ∘ y −1. So both definitions of harmonic coordinates, as given above, have the qualitative ...

Army improved to 8-3 all-time in bowl games, and its 12 wins are the most in a season in program history. Daily finished his senior season with 32 touchdowns, which topped the previous mark of 31 ...
Natural frequency, measured in terms of eigenfrequency, is the rate at which an oscillatory system tends to oscillate in the absence of disturbance. A foundational example pertains to simple harmonic oscillators, such as an idealized spring with no energy loss wherein the system exhibits constant-amplitude oscillations with a constant frequency.
