Line (caper instrument)
Caper instruments are played by moving the elbow back and forth alternating with off and upstrokes. The reduction marks a painting of the elbow in the direction from the frog to the point (thus after right), the upstroke the line in the other direction (after left).
The designation line is used however often also as synonym for kind of line.
Leopold Mozart, one the first Systematiker of the playing the violin play, writes in addition in its Violinschule:
- If the first fourth welfare TAC width unit with no Sospir (break) begins itself; it sey in the same or unequal Zeitmaase: thus one endeavors to take itself the first note of iedes TAC width unit with the Herabstriche. Even if equal after the Herabstrich zweymal should follow each other.
- After more ieder the 3 the following Sospiren (eighth, Sechzehntel and Zweiunddreissigstelpause) must, if they stand at the beginning of fourth welfare, which Hinaufstrich are used.
These two rules are kept on the whole until today: On stressed Zählzeiten the reduction, on unbetonten the upstroke changed
with the play of the Gambe applies this rule exactly turned around, possibly, because also the elbow is kept wrong here.
