It doesn't make sense to me that the piece should start with a 17 month rest. Surely it doesn't really start until the first note is played?
Beethoven’s 5th symphony (da-da-da-DAA) starts with a rest too, it’s not unusual to notate like this. Many pieces have “pickup” measures which are not complete and much shorter than a full measure. But when the pickup is more than 50% of a normal measure, it’s no longer much of a pickup and starting with a rest to make up the complete measure makes sense.
That's all fine and dandy when you're talking about a genuine piece of music. But for something like this, counting a rest that goes for 17 years is taking it way too far.
