This program contains more than 70 minutes of clear audio instruction with interactive on-screen reference material. Everything is included here to give you a firm foundation to build your blues harp playing. Using Apple Computer's QuickTime™ Player (free download PC or MAC) you are in charge of your learning sessions. Listen to an audio explanation using play/pause and replay buttons. Go on to the next topic when you are ready. Or go to the Menu and jump to the topic you want to work on. It's up to you. You will need a major diatonic 10-hole harmonica in the Key of "A" to play along and learn. Pick one up at your local music store or get one online. 1# The (free) QuickTime Player MUST be installed to launch HarmonicaST SuperTutor. 2# If QuickTime is not already installed, it is available as a (free) download from Apple Computer, Inc. heres the link For Windows users http://www.apple.com/quicktime/download/win.html 4# For Windows users: DO NOT open using Windows Media Player as it will play the audio but does NOT understand interactivity. 5# Click on "HarmonicaST" apple Quicktime movie file in Harplayer folder to start SuperTutor. 6# The file "HarmonicaST.mov" AND the Folder "HarmonicaST.media" must remain together inside the "HarpPlayer" folder order to function properly.
