A great sounding all-round string
3 out of 3 found the following review helpful

Pros: Produces a full, rich, rounded sound. Responsive and yet with the desirable "thick" tone that one wants of a c-string.

Cons: Nothing

Other: It is good to have the c-string with variable tensions for different length violas.

A warm mellow string producing very clean notes

Pros: A warm mellow and deep sound with my 1907 Thomas C Buttcher viola, with clean notes up to 5th position. Took a couple of weeks to completely settle but stays in tune very well. Blends in beautifully with Obligato G and D strings.

Cons: Not cheap bur worth it for such an attractive sound

Other: As others have commented it is the combination of string and instrument under review

OK, but not what I'm looking for

Pros: I'm experimenting with 2 or 3 different types of string to see what works best on my viola. This string gives plenty of volume, with a hard edge to the sound, but sounded a bit muffled as soon as I got out of first position. Not bad, but not ideal either.

Cons: See Pros

A good buy

Pros: Very responsive, a little "metallic" to initial open playing but good tone when fingered.

Cons: It rings sympathetically a lot

Suits the instrument
2 out of 5 found the following review helpful

Pros: This 'strong' tension string suits my instrument better than anything I've previously tried. That is not really a reflection on the string itself, but on the way it interacts with this particular viola. In general, I like the sound of Obligato strings on this viola -- but not on my violin, which is already "dark" enough in sound.

Cons: Nothing, yet.

Other: One can only laugh at being asked to review a viola string at all (given that everything depends on the instrument and context). This one was at least fitted, whereas most string purchases are bought to replace spares.

A fine product for most musical situations
0 out of 1 found the following review helpful

Pros: A soft-tension C-string for my 16.5 inch viola with a string vibrating length of 380mm. Very easy to play, nice tone, usual quality item from Pirastro. Once it has stretched itself it stays reasonably in tune.

Cons: Very slightly 'flabby' when faced with fast/low-pitched/loud passages. The medium tension version (optimised for 370mm) is not significantly 'quicker' (but these comments are very dependent on the viola's 'natural' characteristics).

Other: Similar positives for the Obligato/soft G-string and D-string.
