iMUSE
iMUSE (Interactive Music Streaming Engine) was invented by Michael Land and Peter McConnell at LucasArts and first deployed in The Secret of Monkey Island (1990), then expanded substantially for LeChuck's Revenge (1991).
The system allowed music to transition dynamically: rather than playing a single looping track and cutting to another when the player moved, iMUSE queued musical segments at musically appropriate transition points — bar lines, phrase endings, modulations — so that the change felt natural rather than abrupt.
Entering a new area of Mêlée Island, approaching LeChuck's ghost ship, or solving a puzzle might each trigger a distinct musical response. The result was a score that felt alive and responsive rather than merely decorative.

Later Games
The Curse of Monkey Island (1997) introduced new composers Clint Bajakian and Michael Land continuing in an expanded role. The CD-quality audio allowed for richer orchestration and new arrangements of the theme.
Escape from Monkey Island (2000) brought Michael Land back as sole composer. Despite the troubled development, the score was well-received — particularly the arrangements for Melee Island.
Tales of Monkey Island (2009) featured music by Jared Emerson-Johnson, who adopted and expanded the classic themes while adding new leitmotifs for the Voodoo Pox and the new characters.
Return to Monkey Island (2022) brought Michael Land back for the first time since EMI — scoring a full orchestral and Caribbean-inflected soundtrack that reintegrated the classic themes while creating something new.
