Dr. No (1962) onwards: 'The James Bond Theme' by John Barry and his Orchestra

The first Bond film didn't have its own unique theme tune like subsequent movies (though a portion of the opening credits was accompanied by Byron Lee and the Dragonaires' Kingston Calypso), but did feature the first airing of the instantly recognizable James Bond Theme, which has been used at the start of every Eon Productions James Bond film since, accompanied by the famous gunbarrel sequence. The classic piece, with its signature surf rock guitar riff and brass fanfare, was credited to Monty Norman and originally arranged by and performed by regular Bond composer John Barry and his orchestra for the Dr. No soundtrack. The song was subject of repeated legal wrangles between Norman and Barry as to who actually wrote it.
