You can't play most of the same songs on both. Bagpipes (well, most forms of bagpipe, there are dozens, but unqualified people tend to mean the Scottish "Great Highland Bagpipe") are a diatonic instrument playing a just-intonation scale tuned to not cause discordant notes with their own drones, while guitars are a chromatic instrument fretted to play an equal-tempered intonation. The GHB plays in something rather close to the modern Mixolidian A mode with an augmented 4th, not any of the major or minor keys of modern Western music. The GHB and the guitar are entirely incompatible instruments, unless you're talking about a classical guitar with tied-on gut frets that could be replaced to allow playing the GHB scale.

What you're trying to say is that assembly is like the bagpipes and impractical. What I'm trying to say is that's a terrible metaphor because the main reason to learn assembly is understanding what your non-assembly code is actually executed as.
