You just can't have to much rosin on your bow...especially if your just starting to learn. Work the entire length of bow hair thru the rosin at a fast pace till it warms....then nice slow strokes and you will feel the increased drag. After you learn proper hair tension and pressure (read ten years) you will need less rosin. The rosin that falls to the fiddle top is of no consideration if you paid less than $80,000 for that fiddle. Those that use finger or flat picks will ask for a swipe of rosin dust to make their picks stick to their fingers better. My fiddles look like birds been perching on them....I like that look...those that don't can wipe theirs off with a soft dry rag. Practice in the dark. You'll learn twice as fast. Tune each string down at the end of each session to releive pressure. Tune back up next time you want to play. You will learn tuning unaided by remote pitch and be able to tune up perfect even during a bombing or when others are off pitch. Cheers!
