For a repeat order, keep the article number, instrument size and contents of the packet. For a first trial, define the goal: a different feeling in the middle register, a more comfortable transition between strings, or replacement of a worn set while retaining a familiar approach. The family name narrows the search, but the exact version and your own violin determine compatibility and the playing experience.
Choosing Pirastro Obligato
The standard combination and alternatives
The Pirastro Obligato specification lists a standard full size set with a Goldsteel E, aluminium wound A, and silver wound D and G. The wound strings have synthetic cores. Alternatives include a regular steel E, chrome steel wound A and aluminium wound D. A manufacturer's available option does not necessarily mean that version is currently stocked by the shop.
Read these descriptions precisely. Chrome steel on the alternative A identifies the winding, not a change to a steel core. Goldsteel in the E description does not mean that all four strings are gold coated. When the material matters to your choice, use the full specification for the individual note and its article number rather than a shortened set title.
Choosing an alternative A or D for a reason
Alternative windings allow you to change one part of a set while retaining the others. This can be useful when most of the combination already works well but one transition or register remains less comfortable. Begin with a specific observation, such as difficulty balancing a familiar phrase across D and A. Repeat that phrase after the change rather than testing only an isolated open string.
Change one variable at a time if you want to understand the result. A different D, a new E and different rosin introduced together create several possible explanations. Record the original combination, replace the selected position and compare under familiar conditions. If the old set is substantially worn, establish a sensible reference first: a new string's improvement cannot automatically be attributed to its winding material.
Turning a preference for warmth into a useful test
Pirastro describes Obligato in terms of warmth and fullness. Treat this as a direction for exploration rather than a promise of identical tone on every violin. Clarify what warmth means to you: less edge near the ear, a more substantial middle register, a gentler note beginning or easier blending with colleagues. Those are different musical needs, even when players use the same descriptive word.
Listen for clarity as well. A pleasing sustained note in an empty room does not establish how a phrase will carry among other instruments. Ask a colleague to listen from a distance or assess the change in a real rehearsal. A successful choice should remain understandable and controllable in your actual playing situation, not simply make a strong first impression when you try an open string.
Compatibility checklist
| Parameter | What to check |
|---|
| Size | Check fractional set contents separately from 4/4 |
| A and D | Confirm the winding of the selected version |
| E string | Goldsteel or steel; ball or loop |
| Repeat order | Keep the reference and actual set configuration |
Size and the contents of fractional sets
The catalogue includes Medium for 4/4 and fractional groups 3/4–1/2 and 1/4–1/8. An important distinction is that the fractional options table lists a regular steel E. Do not automatically transfer the standard full size set description to smaller instruments. Check the contents of the precise size and product version being ordered, even when every packet carries the Obligato name.
Choose size from the instrument rather than the player's experience or age. A student can move to a different violin while retaining a preferred string family, but the old article number may no longer be appropriate. Ask the teacher to put the required size on the shopping list. Medium is neither an experience level nor a universal numerical tension shared by all brands.
E material and attachment are separate decisions
After selecting an E version, check the required ball or loop attachment for the full size product. The material does not establish compatibility with a particular fine tuner. Inspect the existing attachment and compare it with the product description. If the previous packet is missing, a photograph of the fitting helps you ask a precise question instead of guessing from the instrument's overall appearance.
There is no requirement to use one E with every possible Obligato combination. Some players retain a familiar E while trying the other three positions so that the upper register remains a stable reference. Record such a mixed set separately. Otherwise a future purchase of a standard pack may differ from your usual combination even though the family name on the box is unchanged.
Evaluating Obligato in lessons, ensembles and recording
A lesson is a useful place to compare quiet note beginnings, slow bowing and string crossings. In an ensemble, listen to how clearly your line is heard and how it interacts with the other parts. When recording, keep microphone position and settings consistent so that a change in recording technique is not mistaken for a change in strings. Each setting answers a different practical question.
Prepare two short excerpts: a sustained melodic phrase and a passage with frequent crossings. Use familiar tempo and dynamics rather than playing louder to justify the purchase. Note specific improvements and difficulties. If a change works particularly well in one register, that is useful information for choosing an individual string later, rather than an automatic reason to accept or reject an entire family.
Replacement timing and care
Leave time between installation and an important performance. There is no adjustment schedule that suits every violin and player. If you have not changed strings before, ask a teacher or instrument specialist for help. Check more than tuning after fitting: look for obvious problems at contact points and pay attention to repeated damage in the same location, which may require an instrument inspection.
A synthetic core does not remove the need to care for a wooden instrument. Material stability claims should not be interpreted as permission to expose the violin to unsuitable storage conditions. Use care methods compatible with both strings and finish, avoiding improvised solvents near varnish. Keep packets and installation dates so that you can order a precise replacement and relate a changing response to normal use.
Keeping useful spares for a mixed set
If you use an alternative A or D, label its spare separately from a standard set. A short record can include the family, note, winding and article number; add the attachment for the E. This is especially helpful before travelling, when somebody else might need to find an exact replacement without reconstructing your preferences from a vague description such as “warm synthetic strings”.
Avoid collecting unidentified spare strings in one packet. An unknown string cannot confidently be treated as equivalent to a specified item. Prepare essential spares in advance and check their markings. Having four spare strings in a case is not by itself proof that they form a suitable set for the violin you currently play.
Ordering at SoundsGood
Check the instrument, size, note or set contents, relevant material, E end and current terms of the individual listing. Obligato is also a family name for other orchestral instruments, so the violin designation matters. Browse the broader violin strings category for comparison, or use SoundsGood contacts to clarify an article number. New rosin is not automatically required if the product you already use works well.
Are all Obligato sets identical?
No. Contents can differ with size and E version, while individual strings also have alternative windings. Match the article number and the actual contents of the chosen packet.
Does the Chrome Steel A have a steel core?
In that Obligato version, chrome steel describes the winding. The core remains synthetic, so shortening the description to “steel A” can be misleading.
Does a fractional set necessarily contain a Goldsteel E?
No. The manufacturer's fractional table lists regular steel E strings. Check the specific size and contents instead of applying the full size set description to every version.
Can I replace only the D?
Yes, provided the size and version suit the instrument. This allows one controlled change, although the condition and age of the remaining strings must also be considered.
Will Obligato definitely make my violin warmer?
The manufacturer's description helps define a direction, but the result depends on the violin and player. Compare familiar excerpts and, where possible, include a listener at a distance or an ensemble rehearsal.
