This App is spectacular. My wife and I began singing later in life, mostly classical works. Anytune makes learning complex passages so much easier by filling in a crucial step in the learning process. Learning the notes is one step. Getting all those fast notes up to performance tempos is where Anytune is so helpful. The ability to slow down the tempo, get the notes where they should be, and then slowly get the tempo up to proper speed really shortens the learning curve. The App is easy to use. Also, transcribing florid cadenzas is now a breeze.
