If you attend the Idaho Bach Festival starting Tuesday, youll hear a five-string cello for what is likely the first time in your life.

You wouldnt have heard one before now because cellos dont have five strings; they have four. But this wasnt always the case.
Back in the day, the very idea of a cello was a fluid concept, said Miranda Wilson, an associate professor of cello at the University of Idaho and co-director of the Idaho Bach Festival. Wilson explained that it took a while for people to figure out the optimal form and function of a cello. During the 1700s, when Bach was around, some cellos had four strings and others had five. The shape and size varied as well. So, music written for a cello would have been played on a variety of cello-like instruments.

The role of the cello has also evolved. Back then it wasnt considered a solo instrument, Wilson said. It functioned more like the electric bass keeping beat in a modern rock and roll band -- which is why it was unusual when Bach wrote Six Suites for Solo Cello.
Because the final suite is written for the five-string cello, its a very difficult piece for modern cellists to play, and they have to omit certain notes. However, Tuesday night at the Idaho Bach Festival, listeners can hear Six Suites for Solo Cello in its complete form when Wilson plays on her five-string cello.
She had long been curious about the five-string cello. There are just a handful of them out there. For the most part, original instruments from that era have been broken, lost or altered, and the consensus among those whove made custom instruments is that they just dont sound good. Wilson wasnt satisfied with that.
With a grant through UIs CLASS/ORED Transformative Research and Investment Partnership, she had a custom cello made by Luis & Clark in Boston, Mass. The cello is made from carbon fiber rather than wood -- which may account for the fact that Wilson describes its sound as really very good.
The added string is on the higher tonal end, which means the cello can produce higher, more resonant sounds -- a bit like a violin. No other stringed instrument can produce that range of sound.
The result is like if a cello and violin got together and had a baby, Wilson said.
The strings are closer together, making it challenging to play. Which is to say, youre not likely to see five-string cellos make a comeback anytime soon.
