Cello string tensions

This table shows the tensions that result from the different gauges available for the cello. The string length is assumed to be about 68cm and the pitch standard is assumed to be a-415. If the string length on your instrument is a little longer, then the tension will be a little more. If the string length on your instrument is a little shorter, then the tension will be a little less. You can use this table to find out what sort of tension you are using on your cello. Each string is listed with a type of gut that is used on the instrument. There are two listings for the G-3 and C-4 strings. There is one listing each for wound strings and for plain gut strings.
