Though this is by no means a formula for righting prog music an example without getting to much into music theory would be having light, airy, jazzy, exotic clean chords, and chord structures. These are normally panned into the background making it sound distant with added echo and reverb. Next there would be a very djenty, rhythmic guitar and bass patterns riff/ pattern going on usually panned to your left and right soundscape. Sometimes

    from I’ve decided to choose a select few that I’ve found appealing to me. Math rock is a rhythmically complex, guitar-based style of experimental rock music that became known in the late 1980’s. It is distinguished by complex, atypical rhythmic structures including irregular stopping and starting, sharp melodies, and dissonant chords. The sound is usually dominated by guitars and drums as in traditional rock, and because of the complex rhythms, drummers of math rock groups have a tendency to stick

    The ZnO crystallizes in a few forms which are wurtzite, zinc blende and rocksalt as shown in Figure 2.4. The wurtzite structure is the most thermodynamically stable phase under ambient temperature and also very common. The zinc blende ZnO geometry can be stabilized only by growth on cubic lattice substrates and the rocksalt structure (NaCl structure) can be obtained at relatively high pressures using ultrasonic wave velocity measurements of up to 10 GPa.
