Stratus cloud Stratus cloud Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals. More specifically, the term "stratus" is used to describe flat, hazy, featureless clouds of low altitude varying in color from dark gray to nearly white. The word "stratus" comes from the Latin prefix "strato-", meaning "layer". Stratus clouds may produce a light drizzle or a small amount of snow. These clouds are essentially above-ground fog formed either through the lifting of morning fog or through cold air moving at low altitudes over
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
