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 ...
"The number of the notes that make up a scale as well as the quality of the intervals between successive notes of the scale help to give the music of a culture area its peculiar sound quality." [ 6 ] "The pitch distances or intervals among the notes of a scale tell us more about the sound of the music than does the mere number of tones."
A musical passage notated as flats. The same passage notated as sharps, requiring fewer canceling natural signs. Sets of notes that involve pitch relationships — scales, key signatures, or intervals, [1] for example — can also be referred to as enharmonic (e.g., the keys of C ♯ major and D ♭ major contain identical pitches and are therefore enharmonic).
The naming of individual Cs using the Helmholtz system. Helmholtz pitch notation is a system for naming musical notes of the Western chromatic scale.Fully described and normalized by the German scientist Hermann von Helmholtz, it uses a combination of upper and lower case letters (A to G), [a] and the sub- and super-prime symbols ( ͵ ′ or ⸜ ⸝) to denote each individual note of the scale.
The system is an example of the difference between the treatment of dissonance in jazz and classical harmony: "Classical treats all notes that don't belong to the chord ... as potential dissonances to be resolved. ... Non-classical harmony just tells you which note in the scale to [potentially] avoid... meaning that all the others are okay". [4]
