Writing and decoding music – Piano Companion: Chords,Scales Review

I use this app most when I am about to set up a score of music. The shear amount of information in this free app is incredible. I used this app on multiple occasions to figure out what key a score was written in and what type of scales were used in runs. Let me provide an example, from the movie The Terminal, the main soundtrack is written in a D minor key, and towards the end of the song the lead clarinet plays a D genus diatonicum veterum correctum (yes this is a real thing) scale pattern. Application is very helpful
