Selected Cello String Tensions 1922-2018

If using a mobile, please rotate to landscape to see the whole table – or if you’re in portrait view, just scroll left to view all columns.

* NB Most manufacturers publish string tensions for A-440Hz tuning and a vibrating string length of 700mm. However, Pirastro’s published data is based on a 690mm string length. We would like to thank Professor Jim Woodhouse of Cambridge University’s Engineering Department for confirming that 3% is the correction to apply to make Pirastro’s data comparable to other manufacturers. We have stated the adjusted figure in brackets after Pirastro’s published data.
