Report 5-string Instruments. Why/why not? in The Pegbox Posted January 5, 2021 On 1/3/2021 at 9:30 PM, Marty Kasprzyk said: I made a 17.5 inch 5 string viola last summer and I just finished one that is nearly identical but with only 4 strings. I thought they sounded quite similar. A student has them now and he will be making a video of him playing each of them. You can go the other way and take a string off of a violin or viola to see if the sound changes much on the remaining 3 strings. You can extend this idea and take two strings off to see how the remaining two strings sound and so on. But I found that if I took off all four strings the results were disappointing. I would bet that playing the 5 string feels different than the 4 string in terms of the response or playability.
