MUSICAL NOTATION

A (musical note)

From Wikipedia, the free encyclopedia

 

A is the sixth note (submediant) in the C Major scale. "A" is generally used as a standard for tuning. When the orchestra tunes, the oboe plays an "A" and the rest of the instruments tune to match that pitch. Every string instrument in the orchestra has an A string, from which each player can tune the rest of their instrument.

"A" is also used in combination with a number (e.g. A-440) to label the pitch standard. The number designates the cycles per second of sound waves. A lower number equals a lower pitch.

By an international treaty signed in 1939, modern pitch is standardized at A-440. However, tuning has varied over time, geographical region, or instrument maker. In seventeenth-century Europe, tunings ranged from about A-374 to A-403, approximately two to three half-steps below A-440. Historical examples exist of instruments, tuning forks, or standards ranging from A-309 to A-455.3, a difference of almost six half-steps. Although the official standard today is A-440, some orchestral groups and chamber groups prefer to tune a little higher, at A-442 or even A-444. Baroque pitch is usually cited as A-415, which is a half-step lower than modern pitch.

A0 is the lowest note on the piano. The octaves follow A1, A2, etc. with A7 being a few pitches lower than C8, the highest note on the piano. The note "A" is not considered to be a certain milestone or mark to hit with voice as, for example, Tenor C is, but it can be extremely demanding in certain octaves.

Common scales beginning on A

  • A Major: A B C# D E F# G# A G# F# E D C# B A
  • A Natural Minor: A B C D E F G A G F E D C B A
  • A Harmonic Minor: A B C D E F G# A G# F E D C B A
  • A Melodic Minor: A B C D E F# G# A G F E D C B A
