Octave (liturgical)
"Octave" has two senses in Christian liturgical usage. In the first sense, it is the eighth day after a feast, reckoning inclusively, and so always falls on the same day of the week as the feast itself. The word is derived from Latin octava (eighth), with dies (day) understood. In the second sense, the term is applied to the whole period of these eight days, during which certain major feasts came to be observed.
Octaves, not being successive, are quite distinct from eight-day weeks, but are associated with Christian celebration of "the eighth day".
Early history
The "eighth day" or octava dies simply refers to a full seven-day week in the inclusive counting system used in Latin (just as the ninth day completed a nundinal cycle, the eight-day week of the pre-Christian Roman calendar).
The number "eight" may however also have been taken as a reference to the Resurrection, or a "new creation" following the second coming of Christ. For this reason, early Christian baptistries and tombs typically were shaped as octagons.
Octave
In music, an octave (Latin: octavus: eighth) or perfect octave is the interval between one musical pitch and another with half or double its frequency. It is defined by ANSI as the unit of frequency level when the base of the logarithm is two. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music", the use of which is "common in most musical systems".
The most important musical scales are typically written using eight notes, and the interval between the first and last notes is an octave. For example, the C Major scale is typically written C D E F G A B C, the initial and final Cs being an octave apart. Two notes separated by an octave have the same letter name and are of the same pitch class.
Three commonly cited examples of melodies featuring the perfect octave as their opening interval are "Singin' in the Rain", "Somewhere Over the Rainbow", and "Stranger on the Shore".
The interval between the first and second harmonics of the harmonic series is an octave.
Octave (horse)
Octave (foaled April 13, 2004, in Kentucky) is an American thoroughbred racehorse. She was sired by Unbridled's Song, who in turn was a son of 1990 Kentucky Derby winner Unbridled out of the Dr. Carter mare Belle Nuit.
Her only win as a two-year-old came in the Adirondack Breeders' Cup Stakes. She placed second to Dreaming of Anna in the Breeders' Cup Juvenile Fillies in 2006. Then Octave placed second to Rags to Riches in the Kentucky Oaks the following spring and finished second in the Fair Grounds Oaks and the Ashland Stakes.
After five consecutive second places, Octave started winning. After she took the Mother Goose Stakes and the Coaching Club American Oaks, in August, 2007, trainer Todd Pletcher entered her in the final jewel in the Triple Tiara, the 1-mile Alabama Stakes at Saratoga Race Course. Ridden by John Velazquez, Octave lost a stretch dual by Lady Joanne and Lear's Princess and finished third after a steward's inquiry upheld that Lady Joanne did not squeeze out Octave.
