A waterway is any navigable body of waters. Waterways can include rivers, lakes, seas, oceans, and canals. In order for a waterway to be navigable, it must meet several criteria:

Vessels using waterways vary from small animal-drawn barges to immense ocean tankers and ocean liners, such as cruise ships.

Canals are artificial waterways that are constructed to provide a new path of travel for vessels (as opposed to improving a natural waterway along its current course). At one time, canals were built mostly for small wooden barges drawn by horses or other draft animals. Today, major canals are built to allow passage of large ocean-going vessels (see Ship canal) to connect harbours with or create a shortcut between seas and existing waterways, such as the Kiel Canal between the North Sea and the Baltic Sea, which is the most heavily used canal worldwide.

Ludovico Einaudi OMRI (Italian pronunciation: [ludoˈviːko eiˈnaudi]) (born 23 November 1955 in Turin, Piedmont) is an Italian pianist and composer.

Einaudi was born in Turin, Italy. His mother played to him on the piano as a child. He began his musical training at the Conservatorio Verdi in Milan, gaining a diploma in composition in 1982. That same year, he studied with Luciano Berio and gained a scholarship to the Tanglewood Music Festival.

After studying at the Conservatory in Milan, and subsequently with Berio, he spent several years composing in traditional forms. In the mid-1980s he began to search for a more personal expression in a series of works for dance and multimedia, and later for piano. His music is ambient, meditative and often introspective, drawing on minimalism, world music, and contemporary pop. He has made a significant impact in the film world, with four international awards to his name.^{[citation needed]}

His father, Giulio Einaudi, was a publisher, and his grandfather, Luigi Einaudi, was President of Italy between 1948 and 1955. He currently resides on a vineyard in the Italian region of Piedmont.
