The Time Length of This Process

A LIFETIME.

It may seem like that, trust me.
It seems like you may learn one thing today, but forget another the next day. But you just have trust that all the time you've spent in the practice rooms can really pay off someday.

It requires a lot of commitment to be a great opera artist. You don't just need the talent, you need the patience, determination, and perseverance.

Daily practice: 3 hours the least
Daily research: 4 hours the least
-Language, composer style, listening to other interpretations, history of the musical piece
Preparation for a recital program: 1-2 years the least

Preparation for an operatic role: 4-5 years the least
Opera companies usually begin planning the opera production 4 years in advance.
Casting begins 2 years before production.
Opera singers rehearse for 14 days of less with the conductor, director, set and costume designers.
After these 14 rehearsals, they begin working with the stage setting and character make up
Dress rehearsal 2 to 3 days before the performance

These time lengths does not include the psychological and physical battles that you may have to fight during the process.
Artists are very sensitive and emotional individuals. They must learn how to separate their daily personal emotions the moment they go on stage. Psychological and mental break downs are one of the main factors that cause inconsistencies and difficulties for many great artists.

Most opera singers seek help by finding themselves counselors and therapists to stabilize their emotions.
