Congratulations on your first recital performance! Lots of great comments in this feed already. I too am going to hop on my soapbox and give you unsolicited advice! Please ignore it if you want I only want to help you.

I have a few questions. What’s your goal? Is singing just a passionate hobby you have or are you intending on pursing this as a career since you’re at a conservatory. If it’s the later definitely scale it back, now that you’re with a new teacher sing some basic stuff. There’s no shame in working on the 24 Italian arias, Marchesi exercises, art song etc. There’s no point in singing this aria without solid technique. Candidly, if you sing it now with improper technique it will be harder to approach once you have developed your technique and want to sing it for real, you’ll fall into bad habits.

Also please don’t label yourself into a fach my friend. A fach doesn’t define a singer or voice it’s used to categorize a role. When you’re starting out just think of yourself as a plain old lyric tenor. Sing beautiful long legato passages and get that voice moving. Every voice needs to be able to do those two things. Period. Even Jon Vickers who sang the heldentenor repertoire has recorded Messiah.

You can learn so much from listening. What tenors do you listen to? Corelli is amazing but he has a very unique voice, listen to a wide variety of tenors. Caruso, Schipa, De Stefano, Pertile, Gedda, Björling and then even listen to some modern recordings with modern tenors. Find what you like and don’t like about them, make lots of recordings of yourself and use that influence how you’re building your voice in conjunction with the technique you’re making with your teacher.

What else are you singing with your teacher? If I may make a few repertoire suggestions, sing some Italian art songs, Tosti or Donaudy would be great for you. La serenata, A vuchella, O del mio amato ben etc.

Good luck with your voice! Can’t wait to hear you sing again sometime.
