A violinist's fingersFeatured science projectScience project video

Conclusion

The hypothesis that  violinists  have longer fingers on their left hands, while  non-violinists have  shorter left hand fingers, is proven to be true.

Bones are a vital part of our body for many reasons. Involvement in sports and activities that result in stress on our bones, like  baseball  or playing musical instruments, are believed to increase the length and size of our bones.

Also consider

What would happen if the science project was repeated by comparing the finger length of musicians who play other instruments like the guitar or piano?

Try repeating this science project by measuring the arm length of baseball pitchers.
