three elements of music

Pitch - refers to the pitch of the sound

Loudness - the intensity of sound

Timbre - the quality and characteristics of sound

The three elements of musical sound - tone

Pitch: the pitch of the sound

Experimental study one

As shown in the picture, press a saw blade on the table, with part of it extending out of the table. Use your hand to move the end that extends out of the table. If you turn the saw blade lightly or hard, which one will vibrate more? When did you hear the sound?

The three elements of musical sound - tone

The pitch is related to the vibration frequency of the sound-emitting body: the greater the vibration frequency, the higher the pitch; the smaller the vibration frequency, the lower the pitch.

Experiment 2: Use a plastic piece to pull the comb teeth at different speeds. Think about the relationship between the speed of the comb tooth vibration and the pitch of the comb.

Conclusion: The pitch of the pitch is determined by how fast the object vibrates.

Pitch: Refers to the _______ of the sound, _______ is related to the _______ of the vibration

Frequency: refers to the speed of vibration, that is, the number of vibrations in 1 second.

The unit of frequency is Hertz (Hz)

Pitch is related to the frequency at which the sound emitter vibrates:

The thicker and longer the body is, the slower its vibration frequency is, _______.

The smaller and shorter the object is, the faster its vibration frequency is, _______.

The three elements of music - timbre

Tone: (also called tone)

Timbre reflects the quality and characteristics of the sound.

The sounds emitted by different sound emitters have different timbres.
