When I got home last night I gave this a shot on mandolin and it sure is an ear and finger buster! I had to use some extra brain power to get through it, although some of it came surprisingly easy. The phrase is do - la - sol, la - sol - mi, sol - mi - re, do. Numerically, this is 1 - 6 - 5, 6 - 5 - 3, 5 - 3 - 2, 8. Listen to the audio sample below and then try this out for yourself!
There are many great tips along the way, including what Matt calls "internal hearing", and I haven't even gotten to the last two CDs yet. This is definitely one of the better music practice book/CD sets I've come across. What a novel concept - a music instruction book that is actually almost 100% audio!
At $60 suggested retail, it's a little expensive, but there are some used copies on Amazon for under $25. Well worth it, considering the content within is as valuable as several lessons with an instructor. You can also download the audio from Homespun Tapes.
