Figure 1. The notes A flat and A double flat on the treble clef. In Music, the term note has two primary meanings 1 a sign used in Musical notation to represent the relative duration and pitch of a Sound; A clef (from the French for "key" is a musical symbol used to indicate the pitch of written notes.

In music, flat means "lower in pitch. Music is an Art form in which the medium is Sound organized in Time. " More specifically, in music notation, flat means "lower in pitch by a semitone (half step)," and has an associated symbol (), which looks somewhat like a lowercase "b". See also Modern musical symbols Music notation or musical notation is any system which represents aurally perceived Music through the use Pitch represents the perceived Fundamental frequency of a sound A semitone, also called a half step or a half tone, is the smallest Musical interval commonly used in Western tonal music and it is considered the The Unicode character '' (U+266D) is the flat sign.

Under twelve tone equal temperament, C flat for instance is the same as, or enharmonically equivalent to, B natural, and G flat is the same as F sharp. Equal temperament is a Musical temperament, or a system of tuning in which every pair of adjacent notes has an identical Frequency ratio. In modern Music and notation, an enharmonic equivalent is a Note ( enharmonic tone) interval ( enharmonic interval) or In Musical notation, a natural sign ( is an accidental sign used to cancel a flat or sharp from either a preceding note or the Key signature In Music, sharp means higher in pitch More specifically in Musical notation, sharp means "higher in pitch by a Semitone (half step" Note that in any other tuning system, such enharmonic equivalences in general do not exist. In Music, there are two common meanings for tuning: Tuning practice, the act of tuning an instrument or voice

Double flats also exist, which look like double flat and lower a note by two semitones, or a whole step. Less often (in for instance microtonal music notation) one will encounter half, or three-quarter, or otherwise altered flats. Microtonal music is Music using microtones — intervals of less than an equally spaced Semitone. In Music, an accidental is a Note whose pitch (or Pitch class) is not a member of a scale or mode indicated by the The Unicode character '𝄫' (U+1D12B) represents the double flat sign.

Although very uncommon and only used in modern classical music, a triple flat can sometimes be found. It lowers a note three semitones.

The note A flat is shown in musical notation in Figure 1, together with A double flat. In Music, the term note has two primary meanings 1 a sign used in Musical notation to represent the relative duration and pitch of a Sound; See also Modern musical symbols Music notation or musical notation is any system which represents aurally perceived Music through the use

In tuning, flat can also mean "slightly lower in pitch". In Music, there are two common meanings for tuning: Tuning practice, the act of tuning an instrument or voice If two simultaneous notes are slightly out of tune, the lower-pitched one (assuming the higher one is properly pitched) is said to be flat with respect to the other.

An easy way to remember the order of the flats (B,E,A,D,G,C,F) is by taking the first letter of each word in the following sentence. Battle Ends And Down Goes Charles' Father. You can also use the same sentence backwards for the order of sharps. Play an A and an A flat
