Elena - Milan, Italy$64
Trusted teacher: Hello! I’m Elena, I’m Italian and I’m an opera singer, currently actively performing in the contemporary field :) On top of my artistic career, which is now 20+ years old, I have 10 years of solid everyday experience in the musical teaching field, with particular regards for online teaching. My specialties are: teaching opera voice and kids’ vocality. For both of these, any level, even absolute beginner is 100% welcome! I’ve been training children and teens ever since I graduated from my position at La Scala children choir at 18 years old. I love working with kids, and it warms my heart to think of how many little faces I have already had the privilege of meeting thanks to this career. I have helped so many access to the children choirs of their respective cities, and with so many many others I have simply participated in their musical learning journey, which makes me equally proud and happy. Teaching adults is a completely different matter, of course, but it’s probably even more thrilling to me because it allows me to spend the day navigating the fascinating routes of lyrical singing technique. I know how opera studies can be confusing - to say the least; I try my best to represent a safe place for anybody who wants to explore this ancient form of art, as well as to clarify its key points and guide my students to building a correct repertoire. I give lessons for any kind of purpose: - learning music - improving musicality - preparing an audition - finding our own voice - overcoming insecurity Everybody is different, so everybody has their own path to go through; I cater my lessons to the pupil’s needs, and even if the method is always classical, I make sure that the hour of lesson is a fun moment as well as a learning experience. Music is life and life is fun! If what you have read interests you, I’m here to answer all your questions, so don’t be afraid: write me and I’ll see how I can help you! During the lesson, we will take the time to get to know each other better, assess levels and goals, and start to work on them already. I can’t wait to meet you!

I had the pleasure of working with Larissa as my personal Luxembourgish coach for one month leading up to my exam. Her dedication and professionalism were truly outstanding. Larissa helped me practice speaking extensively and also prepared me for the listening test, ensuring I was well-prepared and confident in all aspects. She held me accountable for every course, which greatly contributed to my progress. Larissa is a real professional, and I highly recommend her to anyone looking to improve their Luxembourgish skills.
