3d model viola musical instrument - VIOLA MUSICAL INSTRUMENT... by De Espona

The casual observer may mistake the viola for the violin because of their similarity in size, closeness in pitch range (the viola is a perfect fifth below the violin), and identical playing position. However, the viola's timbre sets it apart: its rich, dark-toned sonority is more full-bodied than the violin's. The viola's mellow voice is frequently used for playing inner harmonies, and it does not enjoy the wide solo repertoire or fame of the violin.
