In the debate of rosewood versus ebony, ebony is generally considered superior due to its exceptional durability, density, and tonal qualities. Rosewood, while also highly valued, is often more expensive and can be more susceptible to environmental changes. According to the Forest Products Laboratory, ebony has a density of 1,200 kg/m³, making it one of the densest woods available. This high density contributes to its excellent strength and resistance to wear, which is crucial for instruments like pianos and guitars. Additionally, ebony has a rich, deep tone that enhances the sound quality of musical instruments. While rosewood offers a unique aesthetic and rich tone, its lower density and higher price tag often make ebony the preferred choice for professional instrument builders.
