transposing instruments

[Jatziri Valtierra]

hi everybody, know how to write for transposing instruments (clarinet
in Bes, bass clarinet in Bes, flute in G) without write the key
because I was looking and I don't found nothing about it, all I've
found is written in the traditional form and my writing is atonal
therefore only cause doubt if I write atonal for some instruments and
for the others not

thanks,
Jatziri
