The viola sits a perfect fifth below the violin. Its G, D and A strings share the violin's pitches; the violin's E is replaced by a low C. Viola music is written mostly in alto clef.
How to tune a viola
- Tune the A string to 440 Hz.
- Tune D, then G, then C, using the fine tuners for small changes.
- Check every string again, because each change shifts the others slightly.
Violinists can use the dedicated violin tuner.
