Evaluating Recorded Sounds

As I am currently measuring the study environment’s possible effects to the study results, I have to find a way to evaluate the latter. The outcome of my online course’s 1st level weresupposed to be four recorded exercises:

  • Ex. on open strings (video example only)
  • Scale from G to G on solo strings (graphic, notation, video)
  • A folktune from standard notation (notation, audio)
  • A simple melody by ear (audio example only)

I plan to give 1 to 5 marks to every exercise. The first question I have right now is: should I really take all four into account or would the scale be enough? I guess if I take all four, it cannot make anything worse but it is just much more work. Also, since the exercises were presented in different ways, I could get some interesting connections between some environmental elements and certain exercises.

The second question is about evaluating: which characteristics should I evaluate? In this stage, every student is struggling to play the correct notes with the given rhythm so there is really no point to evaluate any musical aspects. So these characteristics would be:

  • Correct notes
  • Correct rhythms
  • Stable tempo
  • Evenness of tone (volume, sound)?

And the scale would be a 5 step Likert.
