The Violin
There are two ways to change the pitch of the violin: 1. The pegs on the violin can be turned back and forth in order to tune the violin to a specific key. The first string is tuned in G, second - D, third - A, and the fourth - E. Some electric violins come with 5 strings, the fifth coming before G and tuned in the key of C. 2. Below the bridge of the violin rests fine tuning equipment which will make minor adjustments to the pitch.
Yes, the viola is lower in pitch than the violin.
The viola is one-seventh in size of the violin, and the violin is one-fifth higher in pitch.
You correct the pitch by either turning the pegs on the top of the violin or by turning the fine tuners near the bottom of the violin.
The main difference between a viola and a violin is their size and pitch range. The viola is larger than the violin and has a lower pitch range, while the violin is smaller and has a higher pitch range. Additionally, the viola is typically played in the alto clef while the violin is played in the treble clef.
