"The part is all on the C# string [E tuned down a minor 3rd], so it’s really easy to keep it going. Things get a little trickier when you start skipping strings. I didn’t think it was necessary for the part to make it harder than it needed to be, so I kept it all on the C# string so I could pedal along nicely. I kept it at a tempo where I can comfortably play 16th-notes, which is 172 beats per minute. It’s still fast, but once I start getting past 180 BPM, it gets tough."
