Note: If the tune is written in the key of D, play all F's as F# and all C's as C#.If the tune is written in the key of G, play all F's as F# and all C's as C natural. In the ABC format I've included whether the note is sharp or natural (this can also be inferred from the key signature). Because fifing tunes are played in D Major or G Major a lot of people just call F and F# the same thing (as they're always playing an F#).
The notation used in the ABC format is the same as in Gary Hastings book "With Fife and Drum". For example D means D in the middle octave on the fife and D' means D in the high octave on the fife.
Some ABC notations use lower case and upper case letters - but we don't. If you're familiar with the fingering on the fife this quick ABC reference is probably easier to read.
