The soprano saxophone is among one of the smallest in the entire saxophone family. The size of this awesome instrument is about the size of your normal b flat clarinet. Although they are the same size the clarinet, the soprano play much louder then the clarinet can. Also, due to its similar tone to the oboe, the soprano sax is quite often used to replace the oboe in bands. The soprano sax can be bought new for anywhere between $1000 and $5000. They can also be bought used for about the same price. Sometimes in the soprano sax, the neck has a bit of a curve to make it easier on your neck while you are playing.
