Many fiddles have bridges which are flatter on top than those of classical violins. The flatter bridges makes it easier to play chords and to bow quickly from one string to another. The strings are tuned in a variety of ways. A player might even change the tuning for playing different pieces of music. Tunings other than the regular G-D-A-E tuning, such as G-D-G-D or A-E-A-E, are common. One, two or three of the strings may have been used for a drone (continuous note) while playing the tune on the top string(s).
