Fuga

Fuga is a musical technique where a melodic phrase is introduced by one voice or instrument and then imitated shortly after by others, creating a layered, echo-like effect. This form of composition is common in classical music, especially in counterpoint, and helps build complexity and texture. Think of it as a musical conversation: one part says a idea, and others respond with the same idea shortly after, creating a sense of dialogue and movement within the piece.
