Violin intonation on the harmonics), losing the desired tone, brilliance and intonation. String longevity depends on string quality and playing intensity. A violin is tuned in fifths, in the notes G, D, A, E. The lowest note of a violin, tuned normally, is G, or G below middle C. (On rare occasions, the lowest string may be tuned down by as much as a fourth, to D.) The highest note is less well defined: E, the E two octaves above the open string (which is tuned to E) may be considered a practical limit for orchestral violin parts, but it is
String instrument ways to change the pitch of a vibrating string. String instruments are tuned by varying the strings' tension because adjusting length or mass per unit length is impractical. Instruments with a fingerboard are then played by adjusting the length of the vibrating portion of the strings. The following observations all apply to a string that is infinitely flexible (a theoretical assumption, because in practical applications, strings are not infinitely flexible) strung between two fixed supports. Real strings have finite curvature at the bridge and nut, and the bridge, because of its motion, are not exactly nodes of vibration. Hence the
