In graph theory, a biconnected component (or 2-connected component) is a maximal biconnected subgraph. Any connected graph decomposes into a tree of biconnected components called the block tree of the graph. The blocks are attached to each other at shared vertices called cut vertices or articulation points. Specifically, a cut vertex is any vertex that when removed increases the number of connected components.
There are many types of articulation, with each having a different effect on how the note is played. Some articulation marks include the slur, phrase mark, staccato, staccatissimo, accent, sforzando, rinforzando, and legato. Each articulation is represented by a different symbol placed above or below the note (depending on its position on the staff).
