This week's assignment was too produce a score using the online notation software called note flight. I found this program to be very usable and have great potential for classroom.  It works a lot like musecore and is comparable in input method and ease of use.  (It might actually be easier.) it is somewhat limited in the amount of sounds that can be produced for playback but the upside is that all oft he information is online and there is no need to download anything.  I used it on my laptop (PC) and on the iPad through Safari.  Both worked well and the iPad version has a virtual piano keyboard for easy notation much like Notion.  Here is my "bike".
