| Rosin up the bow
I use Carlson rosin which is fairly soft. I'm getting a cake of Kolstein soft with my Ken Smith bow I ordered.
I usually rosin my bow well at the beginning of the day and lightly touch it up by the middle of a second rehearsal.
I hold the rosin in my left hand with the sticky surface facing up. I hold the bow in my right hand in playing position so the hair is facing down. I pull the bow over the rosin so there is just the weight of the bow resting on the rosin and no pressure is required.
I lightly run the rosin down from the frog to the tip and back again a few times. I take an extra swipe along the inside edge of the hair as well as this is the side of the hair that will touch the string when I play a soft passage.
I then do a few short strokes of rosin in the 6-inch sweet spot (around the balance point) where I do 50% of my playing.
Some people don't recommend running the rosin from tip to frog as it might catch the hair and pull out a few hairs. I can only see this being a problem if it's really sticky rosin and you're pressing too hard.
Then I flick the hair a few times with my fingernail to dislodge the rosin dust that will fall off in the first 10 minutes of playing. When you look at the rosined bow, you shouldn't see any powder or lumps, just hair.
I'd rather have the dust fall on the floor than gather on the strings. When the dust gathers on the strings, the bass sounds gritty and the strings are just too sticky making the bow response too unpredictable.
I wipe any accumulated rosin off the strings when ever I can to avoid sticky strings.
Hope this helps. |
