  • Philosophy for the San Marcos High School Orchestra Program

    I want to pass on the love of music that I hold near and dear to my heart to my students so they can go out and have fun making and listening to music as much as I do. When enrolled in the orchestra program, you will learn several integral lessons that you can use in your everyday life such as discipline, the value of hard work, having a positive outlook, responsibility, uniformity, being a role model etc. through these main points:

    • Develop a sense of importance of music in the life of each student
    • Develop self-confidence and self-discipline in each student through positive interaction with teachers and peers
    • Develop the musical potential of each student to the fullest
    • Develop student understanding of stylistic traits of different periods of music
    • Develop self-expression and creativity through practice and performance
    • Develop the highest possible standards of performance for each student in the program
    • Learn proper concert etiquette through participation in and attendance at live performances
    • Develop the ability to work in a group as a team for a common goal
    • Represent our school and community in a positive manner

    Through these main goals, I hope that all my students not only become great musicians, but learn the qualities of how to be a good person and a future leader in our society.
