songs 1.6.4 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The program lies within Audio & Video Tools, more precisely Music Production. We recommend checking the downloaded files with any free antivirus. This Mac application was originally developed by Harmonic Sense.
From the developer:
Songs lets you quickly capture the essence of your chord arrangement for a song by adding chord voicings to song lyrics. In a few clicks, add or change chord diagrams. Drag and drop diagrams to copy or move them to a different location. Songs plays the notes as you enter the chords and automatically suggests chord names and fingerings. When you are done, make a beautiful printout, or export to PDF.
