VGFacts

The jingle that plays when you save your game in a Link Between Worlds is the same noise that plays when you us the "flute" in a Link to the Past, albeit higher pitched and a little faster.

(Not Link playing the flute, but his theme is the noise that plays with the flute as well)


(at 20:02)

Considering the connection between the flute and the Kakariko Village weather vane in A Link to the Past, that's a neat little link between the two games. I imagine Link Between Worlds is full of them.
