This table shows the tensions that result from the standard gauges available for the contra-bass. The string length is assumed to be about 97cm 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 instrument. Each string is listed with a type of gut that is appropriate for the string position.
