Music by Bert Kaempfert. Digital Sheet Music & Digital Playback. Content: In Bonus Files: 1 PDF files of sheet music (for performance with playback), 1 Word file with a link for download of 2 mp4 HD video files for best practice (1 melody video track and 1 playback video track). These HD video files have a BEST quality and a not small size. So we decided for more reliability and for fastest download place these files in a cloud service. In regular files for downloading from the site: 1 melody track mp3 and 1 professional backing track (playalong, playback) mp3. But you can download them from the link in the Word file along with sheet music and video files. Just in case, we duplicated all the content and placed everything in the cloud.
