I've been spending a lot of time recently on Arban's Conservatory Method for Trumpet, (I used to play trumpet). It's a great book, I love the exercises. I've gotten a lot of rhythmic and melodic ideas from playing the exercises. Because I've gotten so into this book recently, I've been neglecting my sight reading exercises in bass clef. Are there any Bass Clef Method books that anyone can recommend. I've heard of Simandl's but wanted to know how it ranks amongst others, or if it is the only one. This would be for BG, although I would have no problem using a DB book if it presented better exercises. Thank you.
