Note names

Note names

In English- and Dutch-speaking regions, pitch classes are typically represented by the first seven letters of the Latin alphabet (A, B, C, D, E, F and G). A few European countries, including Germany, adopt an almost identical notation, in which H substitutes for B (see below for details). (Wikipedia)

Names: C D E F G A B 

Notes on stave

A clef is a musical symbol used to indicate the pitch of written notes. Placed on a stave, it indicates the name and pitch of the notes on one of the lines. This line serves as a reference point by which the names of the notes on any other line or space of the stave may be determined. (Wikipedia)

In the example below are notes located on the four most common clefs (treble, alto, tenor, bass). Octave naming is also included.
