Singing is a skill, and it is important that they are learned in order to be a successful singer, whether it is in choir or as a soloist. There are four basic skill set groups that need to be learned.
Aural Skills
Aural Skills require singers to have an internal understanding of pitches (notes) and rhythm in order to be an effective musician. Skill sets necessary for success in the Hawk Choir Choral Classroom include the following:
Diatonic Major Scale and Intervals
Theory
An understanding of music notation and score is vital to learning any music. Skills that fall under this category include:
Takadimi (Rhythmic Solfege) and Rhythmic Number Counting
Vocal Anatomy and Health
Vocal Performance is when the singer takes notes and rhythms on the page and presents them as music to the audience. Creating vocal music requires an understanding of the anatomy, physiology, and mechanics of air flow over the vocal folds as air comes through through the actuator, causing vibrations which create sounds through the resonator and finally the articulators (mouth, head, tongue) into the air.
Anatomy of the human voice
There are four components to the human voice that are used for speech and singing: actuator, vibrator, resonator, and articulator. Watch this video to get a better understanding of how these components are used by the singer.
Breathing for the Singer
Everything begins with the breath. If done correctly, the singer can create a beautiful, resonant, and healthy sound. This internet link gives a detailed explanation as to the mechanism of breathing when singing.
