Classical Wednesday: Mozart – Vorrei spiegarvi, O Dio! K418 (1783)

“Vorrei spiegarvi, oh Dio!” (K. 418) is a technically demanding concert aria for soprano and orchestra composed by Wolfgang Amadeus Mozart in 1783 for his sister-in-law, Aloysia Weber Lange. Known as an insertion aria, it is a dramatic piece meant to be added to operas, specifically for a scene in Pasquale Anfossi’s Il curioso indiscreto.
