Introduction on sounds

Music is above all made up of sounds, the subject of this chapter. Sounds have several characteristics which are to be known, four more precisely in music.

1 – Frequency

Frequency represents the height of a sound, i.e the note in itself (C, D…). A low-pitched sound has a low frequency, and on the contrary to a high frequency corresponds a high-pitched sound. Mankind cannot hear sounds with a high frequency. Each note of a piano (or any instrument) has a defined frequency. But notes don’t represent every frequencies (you can sing a sound impossible to play on a piano). The frequency of a note, for example the middle do on a piano, is the same all around the world. If your guitar is out of tune, it means the instrument plays sounds that are not at the frequencies of reference. That’s why you need to adjust the strings. In music, we will be talking about pitch.

2 – Amplitude
The amplitude is the intensity of the sound, the volume. I can imagine you know what it means.
3 – Duration

Duration is important in music, as it groups together all the notions of rythm, and has to be very precise. The value, as said in music, is represented horizontally on a score, by signs we will explain in a further chapter.

4 – Timbre

Timbre is very complex in music. Every instrument has a specific timbre. You may understand that a C played by a flute will sound differently than a C played by a trumpet, even if it’s exactly the same note.

With all these characteristics, an endless number of sounds can be produced. These properties are the acoustic wave’s properties. But we are not going to talk about that in depth, because it’s more about physics (perhaps some of you know more about it?). Music tries to make them accessible by a common man. All the signs on a score are visual, yet accurate representations of pitch, intensity, value, and timbre. That’s what will be explained in the lessons, so that you can become a musician.
