How does the Ukuklele work?

When the ukulele is plucked or strummed, the string(s) will start to vibrate. These vibration will be transmitted into the hollow body of the ukulele. The sound is then amplified though the sound hole(s) of the body. The length and/or the thickness of the strings will determine if the sound will be higher of lower. The shorter and thinner the string is the higher the notes will be and the longer and thicker the string is, the lower the sound will be. The length of the strings can be tuned to the right length by adjusting the key on the head of the ukulele. It can also be adjusted by pressing the strings against the frets and changing the notes. The ukulele can play numerous amount of notes depending on the type of ukulele and the type of string tuning that are used. There are no specific amount of notes since there are many different fret types, string tunings, and different amplification system within the ukulele family
