Musical instrument for the determination of the movement of musical works. Used today, J-N. Made by Maelzel (1772-1838). Previously, metronomes based on other systems were used. The Maelzel Metronome (which is referred to as t M. M in) consists of a box-like pyramid-like box with a device similar to that of a simple watch. The front of the box is open. A lengthened length of 40 to 208 is printed on a metal plate. When the weight of the pointer in front of this plate is brought to the front of the plate, the tool makes heavy or heavy ties. At the beginning of each musical piece, there is a figure indicating the movement of the piece, and it is pointed out which value of the note will be taken according to the value of the note (ie, whether it is doublet, quartet or octal). In this way, for example, if a quartet note corresponds to 120 digits, that piece will be executed in a movement that will pass 120 notes in one minute (60 seconds). The tool is operated and subjected to tics. In this way, the verses are determined. In a musical piece, since the same movement has not been maintained from beginning to end, the movement in the method proceedings altogether changes, it is necessary to point out the number of the new movement to which each part will be subjected. But even in this way, the role of the metronome is not absolute. For a piece of music is pessimistic with a number of characteristics called naunce (b. Bk.). The aesthetic value forms and manifests in this way. These naunces do not challenge the metronome’s absolutism. For example cresc. And dim. The movement changes with great speed. All this is not to deprive the role of the metronome. Especially when working on a piece, the metronome immediately gains an absolute value. Fr metronome, Eng. Metronome. Alm.
