Free musical software for mac

What if the band you are working with know absolutely nothing about musical theory or chord composition?

As the engineer do you sometimes need reminding which notes belong to a certain musical scale? Maybe you just want to prove to a certain smug musician that they are not the only one who knows the composition of a "A# minor major 7th add 13" chord...

Choose a root note, then a chord type or scale, and the notes that belong to the selected item will be represented on the keyboard below in a clean and clear manner.

The chord compositions are shown in a way that allows them to be easily read and understood. As a result the voicing of some chords will not be the most logical or pleasant sounding.

The GUIDOLib project aims at the development of a generic, portable library and API for the graphical rendering of musical scores. The library is based on the GUIDO Music Notation Format as the underlying data format. The library takes account of the conventional music notation system and should be flexible enough to include any graphical sign and musical information if necessary.
The GUIDOLib project includes the development of several applications for tasks like displaying/rendering musical scores (GUIDO Noteviewer), playback GUIDO files via MIDI, or the conversion between GUIDO and and other scorefile formats. Another main topic of the project is the development of the portable library and API for graphical score.
