Double bass the "old" German method sounded an octave below where notation except in the treble clef, where the music was written at pitch. The double bass is generally tuned in fourths, in contrast to other members of the orchestral string family, which are tuned in fifths (for example, the violin's four strings are, from lowest-pitched to highest-pitched: G-D-A-E). The standard tuning (lowest-pitched to highest-pitched) for bass is E–A–D–G, starting from E below second low C (concert pitch). This is the same as the standard tuning of a bass guitar and is one octave lower than the four lowest-pitched strings of standard
Virtuoso Violin Virtuoso Violin Virtuoso Violin is a violin-playing machine, invented by Fred Paroutaud for QRS Music Technologies, the same company that produced the first MIDI-compatible player piano. It was first unveiled February 13, 1998. The Virtuoso uses an electromagnet instead of fingering the strings. The electromagnet's position changes the behavior of the vibrating string to attain the desired pitch. The Virtuoso is designed to play a real violin, although its setup requires the strings to be restrung and the bridge to be removed and replaced with a mechanical bridge which controls the string oscillation and bow movement. The Virtuoso Violin is
