x Acoustics x| Violin acoustics: an introduction If you put your finger gently on a loudspeaker you will feel it vibrate - if it is playing a low note loudly you can see it moving. When it moves forwards, it compresses the air next to it, which raises its pressure. Some of this air flows outwards, compressing the next layer of air. The disturbance in the air spreads out as a travelling sound wave. - Read more http://www.phys.unsw.edu.au/jw/violintro.html#First | |

Strings, standing waves and harmonics How do we make musical sounds? To make a sound , we need something that vibrates. If we want to make musical notes you usually need the vibration to have an almost constant frequency: that means stable pitch. We also want a frequency that can be easily controlled by the player. In electronic instruments this is done with electric circuits or with clocks and memories. In non-electronic instruments, the stable, controlled vibration is produced by a standing wave. - read more | |
Articulation and vibrato on the violin Different bowing gestures or articulations give the violin a range of different sounds. The differences are chiefly in the transient sounds at the beginning and end of the notes, and in the envelope: the way the sound varies over time. These are illustrated with sound files and oscillograms. - read more | |
