A '''chord''' in [[music]] consists of multiple [[Note (music)|notes]] played simultaneously, though two notes played simultaneously are usually called an [[interval (music)|interval]].  The notes used to "build" a chord are usually assigned numbers, starting with "1" to denote the "root" note, which provides the name of the chord.  [[flat (music)|Flat]] ({{music|♭}}) and [[sharp (music)|sharp]] ({{music|#}}) symbols are used to alter the position in the [[key (music)|key]] that given notes are drawn from.  In Western music, chords are based upon the interval of the third, whether major or minor.
