I've been playing the guitar for years and the trumpet for just 4 months. I'm amazed at how physically demanding the trumpet is. When I started I couldn't play for longer than 30 seconds (yeah I do mean seconds!) and as for range......? On a guitar you just move down the fingerboard - how easy is that? What I'm wondering is how long does it take to develop a useful playing range. At the moment I can hit a third space C, as long as I'm fresh and have warmed-up properly. How long does it take for beginners to get up to a G above the stave for instance? I realise that different people will progress at different rates; I'm just looking for a ball park figure here. Thanks for your help.
