Vibrato, a typical flute playing technic, is expressed in this book in visible and tangible forms.
There are totally four different folds and three different materials evolved in my book, and every page in my book demonstrates one certain music playing method, such as unison, ensemble, and chords.
Some interactive elements were also introduced into some pages. For instance, the audiences are able to adjust the “drumbeats” as an accompaniment on their own, and they may adjust the range of “chord” in another page as well.
