Alda – Text-Based Programming Language for Music Composition
Sorry to be a downer here, but can someone explain to me what the appeal of these projects are? In the past year or so I've seen a number of text-based music notation projects hit the front page of Hacker News and don't really understand the purpose they are trying to achieve.<p>If I want to transport music notation between software programs, I have MIDI for that, which does a good job of capturing all elements of a performance (keys, timing, velocity, pedals, aftertouch, etc.) These types of notation formats almost always fail to achieve MIDIs precision across all the aspects of a performance.<p>If I want to compose music, I need a format that makes it easy to visualize and manipulate notes in context of the other notes playing across all instruments. DAW piano rolls do a fantastic job of overlaying note information, and traditional combined scores do the same too. Again, text notation usually falls flat here - for example, if you had a large ensemble, and wanted to know which chord was being played on the 2nd beat of the 5th measure, how easily can do you do that? How do you determine if it's an open spacing or closed spacing? How do you determine the root without walking back through all the octave shifts?
