C or Do is the first note of the fixed-Do solfège scale. Its enharmonic is B♯.
Middle C is designated C4 in scientific pitch notation because of the note's position as the fourth C key on a standard 88-key piano keyboard. While other note-octave systems (including those used by some manufacturers of digital music keyboards) may refer to "Middle C" with a different designation, the C4 designation is the most commonly recognized in auditory science and in musical studies[citation needed] it is frequently used in place of the Helmholtz designation c'.
While the expression "Middle C" is generally clear across instruments and clefs, some musicians tend to use the term to refer to the C note in the middle of their specific instrument's range. For example, C4 may be called "Low C" by someone playing a Western concert flute (which has a higher and narrower playing range than a piano), while C5 (523.251 Hz) would be "Middle C". This technically inaccurate practice has led some pedagogues to encourage standardizing on C4 as the definitive "Middle C" in instructional materials across all instruments.
In music, the term note has two primary meanings:
Notes are the "atoms" of much Western music: discretizations of musical phenomena that facilitate performance, comprehension, and analysis.
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 musical 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 traditional 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. 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.
Musical is the adjective form of music. It may also refer to:
