Jennah Vainio has studied composition at the Helsinki University and at the Sibelius Academy. She has also participated in master courses by Magnus Lindberg, Jouni Kaipainen, Brian Ferneyhough, Olli Kortekangas and Sven-David Sandström.

Her pieces have been performed both home and abroad and on the radio. Most of Vainio’s pieces are written commissions.

Her works have been published (Fennica Gehrman, Sulasol, Uusinta) and recorded (Pilfink Records, Alba Records).

A Sweet Escapade and Ankomst till Hades (Arrival in Hades), two pieces by Vainio, have both enjoyed success in international compostion competitions.

Besides classical music Vainio is known for her passion for metal and country music. A guitarist herself, Vainio’s first influences included the neoclassical metal guitarists Yngwie Malmsteen, Jason Becker and Joe Satriani. As an
composer, Vainio feels that it is important to be versatile stylistically.
