Stratus cloud a region. Some call these clouds "high fog" for the fog-like cloud. While light rain may fall, this cloud does not indicate much meteorological activity. Stratus clouds form when a sheet of warm, moist air lifts off the ground and depressurizes, following the lapse rate. This causes the relative humidity to increase due to the adiabatic cooling. Stratus clouds look like featureless gray to white sheets of cloud. They can be composed of water droplets, supercooled water droplets, or ice crystals depending upon the ambient temperature. Stratus nebulosus clouds appear as a featureless or nebulous veil or layer of stratus
Digital sheet music more on the practice and consumption side of music learning. These latter cloud-based applications integrate audio-output such as playback with a variety of tempi (speeds) and with different instrumentation for multi-part scores and make the viewing and playing more interactive by adding personal annotations, automatic page turning, or set lists. Overall, four factors appear to facilitate digital sheet reading: computer, content, containers and controllers (Hugh, 2013): Digital sheet music Digital sheet music is technology for representing and displaying sheet music in a computer-readable format. With the emergence of several technological innovations, sheet music evolved in several stages into what was
