I used to enjoy a capella also, back in my younger days before the demon baccy took away my dulcet counter tenor tones, especially liked one voice per part, madrigals, motets renaissance and baroque mainly. Purcell, Byrd, Wylbye, Thomkins, Bennett, and many others of the period. We did sometimes perform more recent works, I think Britten's Hymn to St Cecilia was about as recent as we got.
Once performed the Messiah in a 30 strong choir, plus soloists, harder work than you might think.
Voice didn't seem to break properly I had no problem singing the Alto range, had more trouble trying to get down the scale if I took a tenor part. I was still able to hit G4 into my late 20s early 30s, (counting middle C as C3) but by age 40, I could only manage E4 unless I had been singing a lot more than usual for a week or more. My fathers voice was the same, he was still taking Soprano solos in a church choir well into his 20s. None of my sons took any interest in singing so don't know if the voice heritage continued.
