That is why material quality and workmanship are essential for playability and durability.  This fingerboard is made from ebony. The dense hardwood has been the preferred choice in violin making for generations due to its durability and excellent playing characteristics.  A reliable foundation for instruments built to make music for many years.   Grade 2:  Functionally sound wood with more pronounced color variations, less uniform grain patterns, and acceptable visual imperfections.   Grade 1:  Selected quality wood with a more consistent structure, improved appearance, and fewer color variations.   Grade 1A:  Carefully selected premium wood featuring highly uniform color, fine grain patterns, and an exceptional visual appearance.",
