Steve's Guitar Lessons: beginning, folk, and classical gui
The art of taking samples or excerpts of musical ideas and combining them selectively is probably as old as music is. This might even be one or the sources of music. On the other hand, clearly many musicians have heard original unique music and written it down as a composition. If you, however, are inspired by parts of the compositions that you have grown to love, join the crowd. Feel free to combine these in whatever way gives you the greatest pleasure. Of course, if you publish a result, then you would want to obtain permission from the publisher, in question. But, from what you say, it just sounds like you like you are interested in gaining some further satisfaction. I wish you the best.
