In just intonation, the frequencies of the scale notes are related to one another by simple numeric ratios, a common example of this being 1 / 1 , 9 / 8 , 5 / 4 , 4 / 3 , 3 / 2 , 5 / 3 , 15 / 8 , 2 / 1 to define the ratios for the seven notes in a C major scale, plus the return to the ...
A graph of the A-, B-, C- and D-weightings across the frequency range 10 Hz – 20 kHz Video illustrating A-weighting by analyzing a sine sweep (contains audio). A-weighting is a form of frequency weighting and the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level.

C pentatonic scale beginning on the I (C pentatonic), IV (F pentatonic), and V (G pentatonic) steps of the scale. [clarification needed] Levine points out that the V pentatonic scale works for all three chords of the standard II–V–I jazz progression. [182] This is a very common progression, used in pieces such as Miles Davis's "Tune Up".
The sound of an organ pipe is made up of a set of harmonics formed by acoustic resonance, with wavelengths that are fractions of the length of the pipe.There are nodes of stationary air, and antinodes of moving air, two of which will be the two ends of an open-ended organ-pipe (the mouth, and the open end at the top).

C = 2.6; C− = 2.17; D = 1.3; F = 0.0; Another policy commonly used by 4.0-scale schools is to mimic the eleven-point weighted scale (see below) by adding a .33 (one-third of a letter grade) to honors or advanced placement class. (For example, a B in a regular class would be a 3.0, but in honors or AP class it would become a B+, or 3.33).
Sea temperatures vary from a low of 13.9 °C (57.0 °F) in February to a high of 25.0 °C (77.0 °F) in August. [ 80 ] The highest temperature ever recorded in Rome was 42.9 °C (109.2 °F) on 18 July 2023.
A base-10 log scale is used for the Y-axis of the bottom left graph, and the Y-axis ranges from 0.1 to 1000. The top right graph uses a log-10 scale for just the X-axis, and the bottom right graph uses a log-10 scale for both the X axis and the Y-axis. Presentation of data on a logarithmic scale can be helpful when the data:
Kahoʻolawe is relatively dry, with an average annual rainfall of less than 26 in (66 cm) [6] resulting from a combination of being too low to generate much orographic precipitation from the northeastern trade winds and lying in the rain shadow of eastern Maui's 10,023-foot-high (3,055 m) volcano, Haleakalā.
