What is Glissandus Magic? Glissandus Magic is an innovative app that offers four musical games designed with pedagogical principles and gamification concepts. It accompanies the sound exploration of the transparent piston flute, allowing interaction through touch or by controlling the air pressure when blowing. In a fun and engaging way, the app enhances phonorespiratory, auditory, and emotional skills. Key Musical Benefits - Develops sound direction awareness - Improves pitch accuracy and listening skills - Stimulates fine motor skills and hand-eye coordination - Strengthens conscious breathing - Encourages creativity and free play Who is it for? çPerfect for children (from 4 years old), young people, adults, teachers, and families who wish to discover the musical possibilities of the transparent piston flute together with the Glissandus Magic app. Main Features of the Glissandus Magic App and the Transparent Piston Flute: Game 1: Play with Your Finger Explore the different sounds you can create and their directionality by sliding or holding your finger on the piston. The integrated tuner (always green) indicates when the sound quality is correct. The note names and their alterations, displayed on the tuner, help position the piston precisely and relate it to the ellipse images. Game 2: Musical Mirror Synchronize your movements with those of the piston on the screen, as if looking in a mirror. Reach the green light by adjusting the air pressure and achieve perfect tuning. Games 3: Musical Journey Choose one of the two images that represent the sound being played. Then move the car — either with your finger or by blowing into the flute — controlling the pressure with the help of the tuner.del afinador.
