Notes separated by an octave "ring" together, adding a pleasing sound to music. The interval is so natural to humans that when men and women are asked to sing in unison, they typically sing in octave. [6] For this reason, notes an octave apart are given the same note name in the Western system of music notation—the name of a note an octave ...
The next lower octave is named "contra". 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 ...
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 ...
In Western music, scale notes are often separated by equally tempered tones or semitones, creating 12 intervals per octave. Each interval separates two tones; the higher tone has an oscillation frequency of a fixed ratio (by a factor equal to the twelfth root of two , or approximately 1.059463) higher than the frequency of the lower one.
The duration (note length or note value) is indicated by the form of the note-head or with the addition of a note-stem plus beams or flags. A stemless hollow oval is a whole note or semibreve, a hollow rectangle or stemless hollow oval with one or two vertical lines on both sides is a double whole note or breve.
For example, C 4 is one note above B 3, and A 5 is one note above G 5. The octave number is tied to the alphabetic character used to describe the pitch, with the division between note letters ‘B’ and ‘C’, thus: "B 3" and all of its possible variants (B, B ♭, B, B ♯, B) would properly be designated as being in octave "3".
In music, letter notation is a system of representing a set of pitches, for example, the notes of a scale, by letters. For the complete Western diatonic scale , for example, these would be the letters A-G, possibly with a trailing symbol to indicate a half-step raise ( sharp , ♯ ) or a half-step lowering ( flat , ♭ ).
Microtonality is the use in music of microtones — intervals smaller than a semitone, also called "microintervals".It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave.
