Transylvania is a track off of Iron Maiden. It's an instrumental that runs for 4:05. Like the majority of songs on the album, it was composed by Steve Harris. Initially Harris had planned to write lyrics to go with the song, but when he and the band played it all the way through, they decided it was find the way it is.
On the remastered edition of Iron Maiden, the intro to Strange World is moved to the end of Transylvania.
