Haydn: String Quartets, Op. 20 "Sun Quartets"

Historically informed performance (HIP) is a performance practice that aims to recreate music using the instruments, techniques, tunings, ensemble sizes, and interpretive habits that were current when the works were first written. Rather than being a fixed sound, HIP is a research‑driven approach that reads treatises, scores, letters, iconography, and archival evidence to decide how to articulate, ornament, tune, phrase, and balance the music. Although it is most closely associated with Medieval, Renaissance, Baroque, and early Classical repertories, HIP has expanded into Beethoven, Schubert, Mendelssohn, Brahms, and even early twentieth‑century music. Core elements include period instruments (or replicas), historically appropriate pitch standards and temperaments, rhetorical phrasing aligned with dance and speech, and improvisatory practices such as extempore ornamentation and continuo realization.
