A Dictionary of Music and Musicians/Augmented Interval

AUGMENTED INTERVAL. An interval which is extended by the addition of a semitone to its normal dimension. The following examples show the augmentations of intervals commonly used:—

{ \override Score.TimeSignature #'stencil = ##f \time 2/2 << \relative c' { c2^\markup { \center-align \tiny Unison. } cis \mark \markup { \tiny { \center-column { Augmented unison. } } } | d1 \bar "||" d2^\markup { \center-align { \tiny { \center-column { Major second. } } } } dis \mark \markup { \tiny { \center-column { Augumented second. } } } | e1 \bar "||" f2^\markup { \center-align \tiny { \center-column { Perfect fourth. } } } fis \mark \markup { \tiny { \center-column { "Augmented fourth," "or tritone." } } } | g1 \bar "||" g2^\markup { \center-align \tiny { \center-column { Perfect fifth. } } } gis \mark \markup { \tiny { \center-column { Augmented fifth. } } } | a1 \bar "||" a2^\markup { \center-align \tiny { \center-column { Major sixth. } } } ais \mark \markup { \tiny { \center-column { "Augmented, or extreme" "sharp sixth." } } } | b1 \bar "||" } \\ \relative c' { c1 ~ c c c c b c ~ c c b } >> }
