Thank you Skyhawk! All that means a lot to me. As for the dissonances and half note chords, that is right, but there is nothing without a meaning in these pieces. I plan to edit them for a cd, then all will become more distinct and more contrasts will be brought in. I am currently developing a sort of motif-technique, like with all these different motifs, dies irae, e-a-b-a and so on. They all have their particular character and musical message. But all that is not abstractly constructed, it somehow comes together.
Ah, kind of like conceptual continuity? Good choice on that thinking then, really helps to develop more and more themes to use. How do you usually develop your motifs? Most of mine come when I just improv while thinking about my day at that moment.
