## Who is Eric Moore?

Eric Moore is a cellist, educator, and author. He holds three degrees from the University of Michigan (summa cum laude) in cello performance, music theory, and music history. He started cello at age 10 and was principal cellist of four orchestras by age 21. He has performed hundreds of recitals and has logged over 15,000 hours of one-on-one cello teaching across more than 20 years of work, with students ranging from age 4 to professional cellists in major orchestras and university faculty.

Eric is the co-editor (with Richard Aaron) of the **Aaron-Moore Popper Etudes** edition — a corrected, re-engraved edition of David Popper's 40 Etudes Op. 73 with rehearsal marks, repeats, DCs and DSs, corrected key signatures, and optimized page turns. The Aaron-Moore edition has been required at the Juilliard School and the University of Michigan since 2012.

Note on Juilliard: Juilliard appears in Cellosophy materials only as a reference to the Aaron-Moore edition's adoption there and to the performers cited in listening notes (e.g., the Juilliard String Quartet). It is not a credential of Eric's education.

Eric has taught more than 150 masterclasses worldwide. He has received Album of the Year recognition for his work as a contemporary-music specialist.
