Savarez Corelli New Crystal 733F Viola Strings

Savarez Corelli New Crystal 733F — A Hard-Tension Silver G for 4/4 Viola

The Savarez Corelli New Crystal 733F is a single replacement G string designed for full-size (4/4) viola. It belongs to the Corelli Crystal series, a line that pairs a nylon core with a silver winding to give the lower strings of the viola a warmer, more focused voice than a plain gut or all-synthetic alternative. The Forte (hard) tension calibration of the 733F is intended for players who want a string that resists the bow more firmly and projects further into a room or ensemble.

Because the Corelli Crystal line is built around interchangeable single strings, the 733F is sold on its own — useful when only the G has worn out, snapped, or needs a tension change, while the rest of the set is still in good shape. It is the hard-tension counterpart to the medium-tension 733M, and pairs naturally with the matching Forte A (731F), D (732F) and C (734F) strings from the same family.

What Sets the Corelli Crystal Viola G Apart

What makes this string distinctive within the Corelli catalogue is the silver-over-nylon construction combined with the Forte tension option. Most synthetic-core viola G strings in this price bracket use aluminium or tungsten windings; the silver wrap gives the 733F a slightly darker, rounder colour on the lowest string of the instrument, while the nylon core keeps the response even and the feel stable under temperature and humidity changes. The Forte tension also makes it a practical upgrade for advanced students and adult players moving up from a lighter factory string.

Construction and Materials — Silver Wound on a Nylon Core

The materials and core construction of a viola G string shape both its tone and how it behaves under the bow. The 733F uses the same silver-on-nylon recipe that defines the Corelli Crystal viola line, with the Forte tension setting it apart from the medium 733M.

• Core Material: Nylon — a synthetic core that stays dimensionally stable across playing conditions, giving the string a predictable feel and a clean, even response.
• Winding: Silver — a silver wrap over the nylon core adds mass to the lowest string of the viola, deepening the fundamental and softening the upper partials for a warmer G.
• Tension: Hard (Forte) — the Forte calibration increases string tension at pitch, giving the bow more resistance and supporting a fuller, more projecting sound.

Fit and Compatibility — 4/4 Viola with Ball End

Viola strings are not interchangeable with violin strings, and the G in particular needs to be matched to the instrument's scale length and the tailpiece or fine tuner hardware. The 733F is built specifically for full-size instruments and uses a ball-end fitting.

• Instrument Size: 4/4 — full-size viola; not intended for 15"–16.5" fractional instruments.
• String Position: G (single replacement string) — replaces only the G of a four-string viola, sold as one piece.
• Ending: Ball End — the integrated ball anchors into fine tuners and tailpieces that accept ball-end viola strings.

Tension and Playing Feel — Why Forte Matters

Tension is one of the most important choices a viola player makes when buying a replacement G. The 733F is calibrated as Forte (hard), which has practical consequences for both the left hand and the bow arm.

• Hard Tension Calibration: Forte — a higher tension at pitch means a firmer feel under the fingers and more resistance for the bow, supporting fuller projection.
• Series Context: Corelli Crystal, Forte tier — sits above the medium 733M in the same line, so players can step up in tension without changing string family.

Who the Corelli Crystal 733F Is For

The Savarez Corelli New Crystal 733F is the right choice for 4/4 viola players who want a single, hard-tension G string with a silver-over-nylon construction. It suits advanced students, adult amateurs, and advancing players who have outgrown a lighter factory G and want more resistance and projection from the lowest string without committing to a full set change. Because it is sold as a single replacement, it is also a practical option when only the G has worn out or snapped on an otherwise serviceable set of Corelli Crystal strings. Players who prefer a softer feel can stay with the medium 733M, while those building a complete Forte set can pair the 733F with the matching 731F, 732F and 734F strings from the same family.

The Corelli and Savarez Heritage

Corelli is the bowed-string brand of the French company Savarez, headquartered in Caluire et Cuire near Lyon. The Corelli line has long been associated with strings for violin, viola and cello, with the Crystal series positioned as a modern synthetic-core alternative to traditional gut strings. The 733F sits within that Crystal family as the hard-tension G for 4/4 viola, carrying forward the silver-on-nylon construction that defines the line.
