In the debate of rosewood versus ebony, ebony is generally considered superior due to its exceptional durability, density, and rich tonal qualities. Rosewood, while also highly valued, often lacks the same level of hardness and resonance as ebony. According to the Wood Database, ebony has a Janka hardness rating of 2,320 lbf (pounds-force), which is significantly higher than rosewood's rating of 1,820 lbf. This hardness makes ebony more resistant to wear and tear, making it ideal for instruments that require a long lifespan. Additionally, ebony's dense and heavy nature contributes to its rich, deep tone, which is highly sought after in musical instruments like pianos and guitars. The tonal qualities of ebony are also attributed to its low porosity, which reduces the absorption of sound waves, allowing for a more vibrant and clear sound.
