Pirastro Obligato Violin String Set, 4/4, Medium - Ball-End / Steel

Pirastro Obligato Violin String Set

The Pirastro Obligato Violin String Set combines synthetic-core A, D, and G strings with a goldsteel or plain steel E string. Four variants pair either E-string material with a ball or loop end. Choose the combination that matches your violin's E-string attachment and preferred material.

For players seeking synthetic violin strings with warmth and tonal detail, Obligato offers a focused sound with rich overtones. The aluminum-wound A and silver-wound lower strings provide a consistent material configuration across these sets. This four-string replacement set suits practice, ensemble playing, and performance. Select a goldsteel E string set or a plain steel alternative, then choose the appropriate end fitting.

Each configuration uses a metal E alongside multifilament synthetic cores, which combine many fine fibers within the remaining strings. The A, D, and G retain ball ends; the loop option applies only to the E. Check your tailpiece or fine tuner before selecting a variant. Pirastro specifies medium tension and 4/4 sizing for these configurations.
