Capturing and analyzing subtle combination tones produced by violins

Published on November 1, 2022

Imagine if you’re baking a cake with two unique flavors – let’s say chocolate and vanilla. When you combine these flavors, something magical happens – you get a whole new taste that’s a blend of both! Well, in the world of music, something similar happens when two musical notes are played together. Our ears can pick up on subtle additional tones called combination tones. And guess what? Researchers have been studying these combination tones produced by violins! It turns out that not all violins are created equal. The higher-quality violins produce much stronger and clearly audible combination tones compared to their lower-quality counterparts. How cool is that? But why do these high-quality violins sound so powerful? Well, it seems that the key lies in their strong air resonance. This means that the way the air vibrates inside the violin’s body amplifies these amazing combination tones. The researchers found that factors like the material used and the crafting techniques influence the strength of this air resonance. It’s like having an exceptionally well-built oven for your cake, making it rise beautifully and taste even better! Fascinating stuff, isn’t it? If you want to dive deeper into this world of musical physics, be sure to check out the full article!

When two musical notes are played simultaneously, the human ear can perceive weak additional tones called combination tones. While less perceivable, objective combination tones are also generated by some musical instruments. Researchers have now used violins to explore these rarely studied objective combination tones. They found that the combination tones produced by higher-quality violins were much stronger and clearly audible and powerful air resonance and violin sound quality are linked. The higher-quality violins produced a stronger air resonance due to several factors, including structural material and crafting techniques.
