The “light” rosin is used more in high temperatures (spring or summer), for “smooth” playing or for solo in chamber music.

The “dark” rosin is used more in low temperatures (autumn or winter), for full-tone playing, in an orchestra, or for great solo concerts.

Melos rosins are tested to “function” effectively under any condition. They are handmade in small batches in Greece from natural ingredients.  Melos “sticky” Rosin  is softer and “bites” the strings stronger than Melos “dark” Rosin.
