Why are musical triangles triangular?

In summary, the shape of musical triangles is most likely due to convenience and efficiency in striking the three sides, rather than any specific physics reason. While a circular shape may produce a different tone, the added effort and materials needed to bend a circle likely outweigh any potential benefits.

Is there any physics reason why musical triangles are triangular, and not circles with gaps (or anything else)? Or is it just tradition.

It's easier to bend a triangle out of a strait rod.

The sound would probably be a bit different but not different enough
to want to go to the trouble of bending a circle.

I think Antiphon is right about the actual reason why it's a triangle, out of convenience, but also it's a shorter distance between the three sides of a triangle than a square or a circle, using the same amount of material, so you can strike it faster.

but the sound would be a different tone for a circle than it would a triangle. I think the sharp angles in triangles effectively make it three different lengths of metal as far as fundamental harmonics is concerned (depending on the material and how it creased).

A circular triangle would be like a longer string, effectively emitting one deep tone instead of three higher tones.
 

Related to Why are musical triangles triangular?

1. Why are musical triangles triangular?

Musical triangles are triangular because their shape allows for a clear and defined ring when struck with a beater. The three sides of the triangle create equal tension, resulting in a pure and sustained sound. Additionally, the shape makes it easier for musicians to hold and play the instrument.

2. Is there a scientific reason for the triangular shape of musical triangles?

Yes, the triangular shape of musical triangles is based on mathematical principles. The shape allows for equal distribution of tension, resulting in a consistent and clear sound. It also helps with the resonance and projection of the sound.

3. Are there other shapes that can produce the same sound as a triangular musical triangle?

While there are other instruments, such as bells and cymbals, that can produce a similar sound to a musical triangle, they are not exactly the same. The triangular shape of the musical triangle is specifically designed to produce a clear and sustained ring, making it unique.

4. Can the size or material of a musical triangle affect its sound?

Yes, the size and material of a musical triangle can greatly impact its sound. A larger triangle will produce a lower pitch, while a smaller triangle will produce a higher pitch. The material also plays a role, with metal triangles producing a brighter and more sustained sound compared to plastic triangles.

5. Are there any cultural or historical reasons for the triangular shape of musical triangles?

While the triangular shape of musical triangles has practical and scientific reasons, it also has cultural and historical significance. The triangle is a symbol associated with the Holy Trinity in Christianity and has been used in religious and ceremonial music throughout history. It has also been associated with magic and mysticism in some cultures.
