I tried singing A4s with mix. I can reach them with chest, but then my throat starts hurting. What I did was I tried singing it very quietly with chest voice! I cracked a lot, then once I didn't I could add more air and make it a very powerful note! I'm not sure if it was in mix or not, but it sounded very chesty! I'll soon be uploading a recording so that you guys could tell me!
Another question! A tenor's second passaggio is around G4-A4 (for high tenors). Does that mean that they can only sing up to G4-A4 in chest, or that they can sing comfortably up to there? Because G4 sounds low for a tenor... just asking! Thanks!
