Ok. Here is the old man's Get Off My Lawn rant:
I don't see the need to vary from standard tuning.
There are numerous articles available online that explains why standard guitar tuning developed. Not going to recap that. If a guitarist wants to be able to bend another semitones or two, there are lighter gauge strings and lower tension strings available for that. But if I hear another guitarist say, "But I need the music to be heavier, man!", it'll take all the self-control I can muster not to slap the crap out of him.
The guitars need to play in their own space in the band's mix. They need to stay out of the bass' range. Most horrible mixes I've heard are a result of having too many sound sources competing for space in the sound spectrum.
I learned this when I was re-voicing midi tracks for the last band I worked with in the NYC metro area in the late '80s and the '90s. I invested a lot of time A) reading and inculcating the Yamaha Sound Reinforcement Manual, and B) applying the principles I learned to make the mix on the midi tracks sound as good as they could. This includes understanding through auditioning voicings that the tracks that sounded good soloed often sounded like poop in the mix, and that the soloed parts that sounded like garbage were often exactly what the mix needed. Hundreds of hours tweaking patches through headphones and the full FOH system taught me more than I could have imagined.
Management of the mix's spectrum is critical to good sound, in ways I never truly understood until I undertook that effort. Having space for each instrument, each virtual instrument, and each human voice in that mix allows the mix to be clear, clean, and adaptable to varying types of rooms that a band might have to play. Live rooms with a lot of glass or mirrors to dead, cavelike spaces were a lot easier to manage once we found these things out.
It isn't only guitarists. Keyboard players need to understand that even if they have 10 fingers, they don't need to use them all at one time (and that key signatures with sharps can be played as well as key signatures with flats). Horns can do that too. And vocalists don't need to transpose a half-step to accommodate their 1/2 octave vocal range.
In short: everyone in a band needs to be a MUSICIAN, to the extent their talent allows. That means:
- know your role
- know your space
- be accommodating, and know when to occupy a different role or space for a GOOD MUSICAL REASON.
End rant. Back to your local station.
