About Concert Pitch
Concert pitch establishes a universal reference point so that instruments across the world can play together in tune. The modern standard of A4 = 440 Hz was adopted by the International Organisation for Standardisation in 1955, though orchestras in different cities still vary slightly — Vienna often tunes closer to 443 Hz, whilst some period-instrument ensembles drop to 415 Hz to replicate Baroque conditions.
