So my band just transposed five tunes to keys that were more comfortable to our singer. It's *way* easier for instruments to play in a different key than having a singer wreck their voice by singing outside their comfortable range. The weird thing is that the songs now sound weird sometimes. I can't use some open strings like I used to but new possibilities have opened. Another thing I remember from my first band that made us sound worse than we had to was that everyone was into playing very loud. If we'd pulled back, we'd have had a more even and interesting sound. What else can bands do to improve (besides rehearsing)?
