glownigger i could spot you a 1000miles away
you can tune to 432 if you like, but everyone you play with has to be on same tune for A
really is a preference thing
think all tones reside on different frequencies so if for example you slide from B to A you would hit the 342 in the process.. man it´s really not that easy to say 440h is bad or good
try what resonates with you, i would advise some bells (wich create more overtones(harmonics) as that seems to be more energetic (my experience) also experiement with major chords rather than minor (they tend to have a positive feeling to them)
aaaaand ? my grandmother said you´re a faggot
the tuning sets the orientation point, but you will hit every Hz in the spectrum with everything you do organicly (analog). try to learn more about sound creation. hitting a single hz tone is not natural (each thing/instrument got their dominant frequencies.. etc)
