Most of my students come in weekly for a 30-minute lesson.  Payments are made in advance for 4-lesson blocks.  I also schedule students who are preparing for specific auditions or performances.   Each lesson is tailored to the needs/goals of the singer.  It might include music theory, sight-reading, vocal exercises designed to warm up and strengthen the voice, and finally, song repertoire.   Vocal exercises are included in every lesson, to aid in development of the voice and to correct any vocal issues that may be present.   A detailed studio policy is provided to each student upon entry to the studio.  For the last 15 years, students have participated in my annual vocal studio recital, allowing students to acquire performing experience, while hearing other singers at varied levels of training.   The performance consists of classical music,  folk songs, and musical theater.
