{"product_id":"thomastik-spirocore-solo-4-4-jeu-s43-247814","title":"STRINGS CONTRABASSES SPIROCORE SPIRAL CORE SET S43","description":"\u003ch3\u003eA Reference Designed for Solo Repertoire and the Demands of Modern Playing\u003c\/h3\u003e\u003cp\u003eIn the world of double bass, certain strings become standards because they meet the practical needs of musicians: tuning stability, consistent response across the entire range, and the ability to \"carry\" both in concert halls and amplified settings. This \u003cstrong\u003esolo tuning\u003c\/strong\u003e set follows this logic: offering a comfortable playing sensation and generous vibration while maintaining controlled tension. The \u003cstrong\u003emulti-filament spiral core\u003c\/strong\u003e is at the heart of this identity, as it enables efficient vibration and a sound that remains lively even in soft dynamics.\u003c\/p\u003e\u003ch3\u003eFor Whom and in Which Styles?\u003c\/h3\u003e\u003cp\u003eThis set is primarily intended for double bassists who play in \u003cstrong\u003esolo tuning\u003c\/strong\u003e (usually tuned a whole step above orchestral tuning), whether for \u003cstrong\u003eclassical repertoire\u003c\/strong\u003e (concertos, sonatas, virtuosic pieces) or contexts where increased presence in the upper register is desired. Thanks to its design focused on \"response + sustain,\" it is also suitable for more cross-genre approaches: \u003cstrong\u003esinging pizzicato\u003c\/strong\u003e, exposed melodic lines, or ensemble playing where articulation must remain clear. Recommended level: \u003cstrong\u003eintermediate to advanced\u003c\/strong\u003e, as solo tuning requires specific landmarks (positioning, intonation, and tension management) and refined right-hand technique, especially with the bow.\u003c\/p\u003e\u003ch3\u003eSound Characteristics\u003c\/h3\u003e\u003cp\u003eThe tonal personality of this set comes directly from its \u003cstrong\u003eflexible multi-filament spiral core\u003c\/strong\u003e. This construction promotes a \u003cstrong\u003elong vibration period\u003c\/strong\u003e : the note \"opens\" quickly and maintains a musical sustain, useful in pizzicato to make the line sing, and valuable with the bow to support clean legato. The perceived \u003cstrong\u003elow inertia\u003c\/strong\u003e also helps achieve a clearer attack: the bow grips with greater control while retaining a flexible feel that facilitates dynamics and string crossings. At medium tension, the balance aims for a relevant compromise: enough hold for projection but without excessive stiffness, contributing to left-hand comfort and more stable intonation in exposed passages.\u003c\/p\u003e\u003ch3\u003eRecommended Compatible Accessories\u003c\/h3\u003e\u003cp\u003eTo get the most out of this set when bowing, a \u003cstrong\u003erosin\u003c\/strong\u003e suited to your bow type and environment (humidity, temperature) helps stabilize grip and sound consistency. A \u003cstrong\u003echromatic tuner\u003c\/strong\u003e is also very useful in solo tuning to secure tuning references and monitor stability over time. Finally, a \u003cstrong\u003esoft cloth\u003c\/strong\u003e after playing helps limit residue buildup (rosin, sweat) and preserves the tactile sensation under the fingers.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr)
