The term "note" can be used in both [[generic]] and specific [[senses]]: one might say either "the piece Happy Birthday to You begins with two notes having the same pitch," or "the piece begins with two repetitions of the same note." In the former case, one uses "note" to refer to a specific [[music]]al event; in the latter, one uses the term to refer to a class of events sharing the same pitch.

Two notes with fundamental frequencies in a [[ratio]] of any [[power]] of two (e.g. half, twice, or four times) are perceived as very similar. Because of that, all notes with these kinds of relations can be grouped under the same pitch class. In [[tradition]]al music theory pitch classes are represented by the first seven letters of the [[Latin]] [[alphabet]] (A, B, C, D, E, F and G) (some countries use other names as in the table below). The eighth note, or octave is given the same name as the first, but has double its frequency. The name octave is also used to indicate the span of notes having a frequency ratio of two. In order to differentiate two notes that have the same pitch class but fall into different octaves, the system of scientific pitch notation combines a letter name with an Arabic numeral designating a specific [[octave]]. For example, the now-standard tuning [[pitch]] for most Western music, 440 Hz, is named a′ or A4. There are two formal ways to define each note and octave, the Helmholtz system and the Scientific pitch notation.[http://en.wikipedia.org/wiki/Note]
