World of music

Music is the combination of different sounds i.e. sounds of different frequencies and amplitudes.

Sing a song that you like or speak something into the microphone and record it. Look at the wiggles on Audacity.

What do the shapes of the wiggles tell us?
Compare the wiggles of loud and low voice.

Project: Make your own music

Now you will create a small 10 second music track of your own by recording sounds on Audacity. You have played around with different objects in Section 1.4 to make various kinds of sounds. You can also create newer sounds by clapping or whistling or some other action. Decide the rhythm and the tempo. A group of sounds (for example- snapping fingers and hitting a plate with a spoon) can be your drum or tabla. A tune that fits in that rhythm will complete the music track - you can hum, sing, whistle, or make music using a design that you made in section 1.4.
 

In the music track that you have just recorded on Audacity, identify the wiggles corresponding to each sound that you used.
