Note value
Encyclopedia
In music notation, a note value indicates the relative duration of a note, using the color or shape of the note head
Note head
In music, a note head is the elliptical part of a note. Noteheads may be coloured completely black or white, indicating the note value . In a whole note, the note head is the only component of the note. Shorter note values attach a stem to the note head, and possibly beams or flags...

Variations

The breve appears in several different versions, as shown at right.

Sometimes the longa is used to indicate a very long note of indefinite duration, as at the end of a piece.

When a stem is present, it can go either up (from the right side of the note head) or down (from the left side, except in the case of the longa). In most cases, the stem goes down if the notehead is on the center line or above, and up otherwise. Any flags always go to the right of the stem.
When two or more notes which would normally have flags (eighth note

Bar (music)
In musical notation, a bar is a segment of time defined by a given number of beats of a given duration. Typically, a piece consists of several bars of the same length, and in modern musical notation the number of beats in each bar is specified at the beginning of the score by the top number of a...

Around 1600 the modern notational system was generally adopted, along with barlines and the practice of writing multipart music in scores rather than only individual parts. In the 17th century, however, old usages came up occasionally.

Origins of the names

The British names go back at least to English renaissance music, and the terms of Latin origin had international currency at that time. Obviously, longa means 'long', and the rest mostly indicate relative shortness. Breve is from Latin brevis, 'short', minim is from minimus, 'very small', and quaver refers to the quivering effect of very fast notes. The elements semi-, demi- and hemi- mean 'half' in Latin, French and Greek respectively, while quasi- means 'almost'. The chain semantic shift whereby notes which were originally perceived as short came progressively to be long notes is interesting both linguistically and musically. However, the crotchet is named after the shape of the note, from the Old French for a 'little hook', and it is possible to argue that the same is true of the minim, since the word is also used in palaeography to mean a vertical stroke in mediaeval handwriting.

The American names are loan translations of the German terms; when American orchestras were first established in the 19th century they were populated to a significant degree by German emigrants.
