Q: I found canon sheet music, and it has two step up symbols on every clef... what? :{ Eh... I forgot to add the link, sorry... :p http://pachelbel.net/street/canonscore/v1.html
A: It is Canon in "D" ... the key signature includes the F# and C# symbols because it is in the Key of D, those two notes are played sharp throughout the piece (in every register) unless there is a cancellation before them. ... Of course the sharp is only half a step up.
