FreeSong2 is visually beautiful, and each set of tones (there are three) are pleasing to the ear. It is simple to create beautiful layered music regardless of your musical ability- With the tones available, you literally cannot play a wrong note! There are two keys to play in: C and D, so it is easily possible to set the app to play by itself while you improvise within the app or on another instrument. I love how the tones can be stacked to make chords, and adding ambient sounds adds to the layering. I use it on both an iPad and an iPhone with great sound.I have used it with music therapy clients by itself, and along with a guitar, rainstick and winds chimes to create a very peaceful setting. I can easily see it being used in a classroom/music room to provide background sounds for books or story telling. I would highly recommend FreeSong2 to use for yourself when you need a calming moment, for your young kids to give them a successful tool to channel their musical creativity, and for use with special needs populations to promote a successful and beautiful experience. I cannot say enough good things about FreeSong2!
