The exceptional E3 "Eagle" alto recorder came into being as the result of a search for a unique alto recorder and the cooperation between Adriana Breukink, Geri Bollinger and the recorder manufacture Küng.
The wide bore, the metal labium, the octave key for the high registers and the key system with e’ foot extension provide for a full and powerful sound.
To allow for ensemble playing with modern instruments, the E3 has a strong lower register and a chromatic range of over 2½ octaves.
