Bolero of Fire
The Bolero of Fire is an ocarina song learnt from Sheik in the Death Mountain Crater. It allows you to warp to the Death Mountain Crater, before the Fire Temple.
The Bolero of Fire is interestingly not a Bolero at all. Bolero, as a musical form, is always in triple time such as Ravel's famous Bolero. The Bolero of fire, though, is in 4.
