I've played Jazz (pizz) and am working now on arco, which I love and definitely improves my pizz. I have a question about down bow markings: if there's a down bow marking over the first quarter note in a measure, but no marking on the other notes, does this mean that you use spiccato (and I hope that I'm using the correct term; I mean where you lift the bow between notes and repeat the down bow for each stroke, as opposed to continuing the down bow). I'm sorry if this isn't clear. It's very hard to explain, but the difference in tone and experience is huge. Just wondering how to read the marking correctly. (When I use what I'm calling spiccato, I get a very strong and vibrant sound - something I've never experienced with the bass. It's incredible.) Sorry to post such a novice question, but I really want to learn to read correctly. Thanks very much.
