Most plankton is microscopic, especially that found in freshwater. Marine plankton have exclusively whole groups of organisms that are very visible to the naked eye, e.g. Ctenophores (sea gooseberries). All plankton is divided into the plant-type plankton, the phytoplankton, and the animal plankton, zooplankton.The latter can be further sub-divided into the temporary and permanent zooplankton. The temporary tends to be those which are larval forms of adults living on the seashore, e.g. barnacle larvae called nauplii.tenophores (sea gooseberries). All plankton is divided into the plant-type plankton, the phytoplankton, and the animal plankton, zooplankton. The latter can be further sub-divided into the temporary and permanent zooplankton.
Trills are great fun to play on the violin. A trill, which involves a rapid alternation between the printed note and the next note above it, often happens near the end of a phrase or movement of music. Trills are musical ornaments, something like the glittery decorations on wedding cakes. A trill really draws the listenerâs attention to a particular note.
The European lute and the modern Near-Eastern oud descend from a common ancestor via diverging evolutionary paths. The lute is used in a great variety of instrumental music from the Medieval to the late Baroque eras and was the most important instrument for secular music in the Renaissance. It is also an accompanying instrument, especially in vocal works, often realizing a basso continuo or playing a written-out accompaniment. The player of a lute is called a lutenist, lutanist, lewtist or lutist, and a maker of lutes (or any similar string instrument) is referred to as a luthier.
