Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
This is a list of the fundamental frequencies in hertz (cycles per second) of the keys of a modern 88-key standard or 108-key extended piano in twelve-tone equal temperament, with the 49th key, the fifth A (called A 4), tuned to 440 Hz (referred to as A440). [1] [2] Every octave is made of twelve steps called semitones.
Notes in it include a prime symbol below the note's letter. Names of subsequent lower octaves are preceded with "sub". Notes in each include an additional prime symbol below the note's letter. The octave starting at tenor C is called the "small" octave. Notes in it are written as lower case letters, so tenor C itself is written c in Helmholtz ...

In telecommunication, a standard test tone is a pure tone with a standardized level generally used for level alignment of single links and of links in tandem. [1]For standardized test signal levels and frequencies, see MIL-STD-188-100 for United States Department of Defense (DOD) use, and the Code of Federal Regulations Title 47, part 68 for other Government agencies.
F Sharp notes. F ♯ (F-sharp; also known as fa dièse or fi) is the seventh semitone of the solfège. It lies a chromatic semitone above F and a diatonic semitone below G, thus being enharmonic to sol bémol or G ♭ (G-flat) in 12 equal temperament. However, in other temperaments, such as quarter-comma meantone, it is not the same as G ♭.
B, also known as Si, Ti, or, in some European countries, H, [1] is the seventh note and the twelfth semitone of the fixed-Do solfège. Its enharmonic equivalents are C ♭ (C-flat) and A (A-double sharp). When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of Middle B (B 4) is 493.883 Hz.
