mySongBook Player is a free software application that gives access to a library of tablature/sheet music available to purchase as well as to an interactive score player to read, learn, and print out legendary songs and current hits. That library has been set up by Arobas Music, creator of the Guitar Pro software, and it offers legal scores written by professional musicians. One can fin new, previously unreleased arrangements for string instruments (guitar, ukulele, bass, and banjo), and full scores with detailed transcriptions of every track in the original pieces. Specially designed arrangements are proposed for beginning as well as for advanced musicians. To make your choice of sheet music, browse the previews and 30-second audio samples, and enjoy unlimited access to a new free score everyday. Scores in mySongBook are available for only $0.99, $1.99, or $2.99 depending on their levels of difficulty and the number of tracks they comprise. For each song you buy, you get the possibility to open it in mySongBook Player to listen to the score at various tempos, mute some tracks, play a chosen selection in loop with progressive increase of its tempo, use the metronome, and choose among different display options for notation (standard, tablature, and slash). A connection to the Internet is needed to access it. From AC/DC to ZZ Top, to Django Reinhardt, new titles will appear online weekly.
