About 300 years ago the _lute_ (Fig. 39) was almost as popular as is the pianoforte at the present day. Originally it had eight thin catgut strings arranged in four pairs, each pair being tuned in unison; so that its open strings produced four tones; but in the course of time more strings were added. Until the sixteenth century twelve was the largest number, or rather, six pairs. Eleven appears for some centuries to have been the most usual number of strings; these produced six tones, since they were arranged in five pairs and a single string. The latter, called the _chanterelle_, was the highest. According to Thomas Mace, the English lute in common use during the seventeenth century had twenty-four strings, arranged in twelve pairs, of which six pairs ran over the finger-board and the other six by the side of it. This lute was therefore, more properly speaking, a theorbo. The neck of the lute, and also of the theorbo, had frets consisting of catgut strings tightly fastened round it at the proper distances required for ensuring a chromatic succession of intervals. The illustration (Fig. 40) represents a lute-player of the late fifteenth century. The order of tones adopted for the open strings varied in different centuries and countries; and this was also the case with the notation of lute music. The most common practice was to write the music on six lines, the upper line representing the first string; the second line, the second string, etc., and to mark with letters on the lines the frets at which the fingers ought to be placed――_a_ indicating the open string, _b_ the first fret, _c_ the second fret, and so on.

The treble-lute was of the smallest dimensions, and the bass-lute of the largest. The _theorbo_, or double-necked lute which appears to have come into use during the sixteenth century, had in addition to the strings situated over the finger-board a number of others running at the left side of the finger-board which could not be shortened by the fingers, and which produced the bass tones.
