Some time ago, I created a pedigree tree that shows the musical genealogy of my former piano teacher, Monica Tessitore. It represents teacher-student relationships as arrows going from top to bottom, converging on the subject of the tree. These links don’t really mean that much because inheritance (of ideas/ideologies, style, technique, etc.) in music education is often not particularly strong, but it is still interesting to see how I am musically “descended” from famous composers. For instance, Béla Bartók is my second-great-”grandteacher” (my great-grandteacher’s teacher). Other nth-great-grandteachers include Liszt (n=3), Chopin (n=4), Beethoven (n=5), Mozart (n=6), Haydn (n=6), and Bach (n=7).

This was compiled for personal use and I didn’t adhere to an academic level of verification, so verify any links before assuming they are correct.

There is also the Mathematics Genealogy Project, which does the same thing for mathematicians using their dissertation advising relationships and sometimes more tenuous links.  It has spawned clones for various other fields; see Academic genealogy on Wikipedia.
