Hi Javier! Basically, you are asking for a concept on how to test your hypothesis, that music affects reading speed and comprehension. Planning your test-series there are several aspects which you will have to consider. First, as you already recognized: which music-styles you will be using in your test. I have often read (sorry, no references here, but probably "Scientific American" would be a good start) that classical music, especially of the baroque-Era (Bach, Vivaldi), tend to help reading and concentration capability. Besides this, I think choosing two or three modern pieces (Rock, Rap, Dancefloor) as a contrast would do. You might want to take music volume into consideration as another possible aspect. You definitely should compare your results to comprehension and reading-speed without music. Second the actual comprehension test. Here I would rely on an existing system or at least take a look at some and let them inspire you. For children in grade-school I can remember that "SRA reading labs" (see:
http://www.sra4kids.com/teacher/reading/index.html) was a very nice system, for older students and adults the "test of english as foreign language - toefl" (see: http://www.toefl.org/rc-pq.html for a few examples) provides a very good test of reading comprehension as one of the aspects tested there. If you don't want to rely on an existing test (or don't have simple access to one), it would be easiest to collect several short texts (taking 2 to 5 minutes to read; famous speeches or short stories are good for this) of similar reading level and devise a set of 5 to 10 comprehension questions. These questions should be multiple choice and consider comprehension of the basic idea ("The text deals mainly with...?", "Which of the following adjectives best describes the text?"), as well as details. Third the actual testing. I would let every person read a text under each reading-situation. It would probably be wise to shuffle the texts and not to use the same four or five for each person. Meaning: Person A reads text 1 with classic, text 2 with silence, text three with Eminem Person B reads text 3 with classic, text 1 with silence and text five with Eminem Person C reads text four with... This way you prevent the different difficulty of the texts from influencing your results to strongly. After each text, the testy answers the questions to that text and then goes on with the next. Forth, the analysis of your results. For this you should have the scores for each person and text, as well as the time a person needed for each of the read texts. Depending on how precise you want the results you can just compare the mean reading time and mean score for each music style, or you can compare the mean-values using a statistical test (probably a T-test according to "Student" would be adequate). I think the last variant isn't to much more work and will look a lot more professional :-) Good luck and have fun!
