Bariolage

From Wikipedia, the free encyclopedia

The bowed instrument musical technique known as bariolage involves quick alternation between a static note and changing notes, that form a melody either above or below the static note. This technique is common to Baroque violin music, where the static note is usually an open string note. Bariolage with the open string creates a highly resonant sound.

In the following example, from a violin sonata by Handel,^[1] the second measure is to be played with bariolage. The repeated A is played on the open A string, alternating with Fs and Es fingered on the adjacent D string.

Another well-known example of bariolage is in Bach's Preludio to the E major Partita No. 3 for solo violin, where three strings are involved in the maneuver (one open string and two fingered notes).

[edit] Unison bariolage

Bariolage can also mean a repeated alternation between the same note on different strings, usually an open string and the same note fingered on the adjacent lower string. Joseph Haydn used this effect in the minuet of his Symphony No. 28, in the finale of the "Farewell" Symphony, No. 45, and throughout the finale of his String Quartet Op. 50, No. 6. It is the unison bariolage passages that give this quartet its nickname The Frog.
