Practice reading music while saving your ship from the asteroids! Note destroyer was designed to allow musicians to practice reading notes in a fun and dynamic way! Choose your clef (alto, bass, or treble) and a staff will be displayed in the lower left-hand portion of the screen. Touch the correct asteroid to destroy it and move on to the next.Note Destroyer allows three different levels of challenges. In Regular Mode, you will have 60 seconds to identify the notes, but be careful-after three misses the round is over! In Hard Mode, you have 30 seconds to identify the notes and can not make a single mistake. In challenge mode, earn high scores by identifying as many correct notes as possible. The round is over after 90 seconds or after one incorrect answer.
