As a composer, Martinelli writes experimental music (with works commissioned by Sibelius Academy, and various festivals in Finland and Estonia, alone or together with Finnish composer Petri Kuljuntausta), incidental music (he wrote for documentaries, radio programs and theatre shows), and popular music (he is songwriter for the Italian singer Anna Maria Castelli).
