Betty Bertaux's works have expanded the body of quality repertoire for young singers. Her original compositions are tonally based and characterised by 20th century freshness. Her folk song arrangements are carefully conceived to capture the essence and spirit of the song material. Betty Bertaux's music combines the best elements of musicality and pedagogical concerns.
Compositions and arrangements are characterized by tonal and rhythmic variety. Often, specific aural and vocal needs are addressed. Compositions encourage singers to explore the expressive elements inherent in all music.
Text choices are made with the young singer in mind. Ranging from children's poetry to traditional folk texts in a variety of languages, they capture the imagination of the young vocal artist.
Compositions range from unison melodies to four- and five-part divisi. A simple vocal/choral line may be enhanced by a rich harmonic foundation provided in the accompaniment. Part work is often realized through canon, descant or counter melodies. Homophonic textural interest is provided in more advanced a cappella pieces.
All compositions show a thorough understanding of the vocal capabilities of young singers. Parts are singable and lie well in the child's voice, and care is taken to develop and use the whole singing range and potential of the child's voice.
