Learning by song means encouraging singing in a playful and natural way, having fun singing and learning to sing, becoming aware of one's vocal organ and shaping it through exercises, regular rehearsals, and performance. It involves learning to learn in a targeted, systematic, and playful way, acquiring not only vocal practice but also music theory content and skills. This is best achieved by singing from the very beginning. The songs, sometimes in German and sometimes in English, are catchy, often awakening the pop star in the singer, making you smile, and always sounding authentic and true to style in melody, harmony, and phrasing. They also come in two keys to achieve, depending on the choral requirements, a natural chest voice or edge voice sound.
