Matching the pitch sensitivity of guitar strings
Dr Jonathan Kemp (University of St Andrews)
When sounding a chord and moving the tremolo/vibrato arm on guitar, the strings typically go out of tune in relation to each other. Surprisingly, to a first approximation, the gauge of the string doesn’t have any effect on the pitch sensitivity when the player alters the string length using a tremolo arm or conventional pitch bend. In this talk I will show how varying the ratio of winding and core diameters can be used to match the sensitivity of strings of different nominal pitches.
