I implemented

• play/pause
• changing the score Key
• changing score tempo
• changing score timesignature (very basic, either 4 beats in a bar or 3 beats in a bar)
• improved some of the error reporting

I have been able to

• complete basic solfege notation parser
• build basic GUI for inputting and playing solfege using web audio api

&quiet

So I completed a crude translation layer to test out playing audio tones directly from solfege. Some notes end up playing on a different octave than intended when the scale is not C major, so I have to fix that
