Question

What type of chord forms when a musician strikes multiple adjacent keys simultaneously ?

A) Polychord

B) Fourth chord

C) Tone Cluster

D) Triad

Answer 1

The type of chord formed by striking multiple adjacent piano keys is a Tone Cluster. The example provided (F, F-sharp, and G) creates beat frequencies of 21 Hz, 22 Hz, and 43 Hz.

Step-by-step explanation:

When a musician strikes multiple adjacent keys on a piano simultaneously, the type of chord formed is known as a Tone Cluster. In the given example, where the keys F (349 Hz), F-sharp (370 Hz), and G (392 Hz) are struck at the same time, we have to calculate the different beat frequencies that occur as a result of these closely spaced notes. The beat frequency is determined by the mathematical difference between the frequencies of the notes being played.

Calculating the beat frequencies for the given notes:

• The beat frequency between F (349 Hz) and F-sharp (370 Hz) is 21 Hz.
• The beat frequency between F-sharp (370 Hz) and G (392 Hz) is 22 Hz.
• Additionally, there will be a beat frequency between F (349 Hz) and G (392 Hz), which is 43 Hz.

Therefore, this discordant combination produces beat frequencies of 21 Hz, 22 Hz, and 43 Hz, each contributing to the characteristic dissonance of a Tone Cluster.
