Music is made of sounds. The sound is everything that pleasantly reaches our ears, giving us a pleasant sensation, like the song of a nightingale, the voice of a singer, the sound of a musical instrument.
When the sensation that reaches our ear is not pleasant, we are hearing a noise .
The characteristics of the sound are three: tone , intensity , timbre
The tone It is the characteristic that makes us distinguish a high (high) sound from a low (low) sound.
- The verse of a bird is sharper than that of a cow.
The intensity It is the characteristic that makes us recognize a strong sound from a weak one (soft)
- The chick's verse is weaker than that of an elephant.
The timbre is the characteristic that makes us recognize one instrument or one voice of the other.
- The sound of a cello is different from that of a drum.
As in spoken language we express ourselves with the words formed by the letters of the alphabet, so in music we use an alphabet composed of seven musical notes.
