I don't think it has been released yet. I first saw it about a month ago on the FMM site. It has said coming in August, but in the description it mentions copies available in September. I have been looking forward to it.
"COMING SOON! Ukulele Masters: James Hill—Duets For One. Duets for One is a collection of 15 ingenious solo arrangements by Canadian ukulele master, James Hill. Each arrangement is comprised of two distinct parts—melody and accompaniment—that you'll learn to play simultaneously on a single ukulele! The 15 songs include classics by George Gershwin, Irving Berlin, Hank Williams, Coldplay and others. Arranged for reentrant GCEA tuning, all songs include ukulele tablature as well as music notation and most can be performed with a simple thumb-picking technique. We expect to have copies sometime in September. Stay tuned!"
The publication date is a bit sketchy, it's not even released at the publisher's shop (fleamarketmusic). But it should be, really soon.
Hill is not only an excellent player, he's also very good in teaching stuff - breaking it down, showing relatively simple things that make complicated music). The version of Freight Train in F does look conspicuously a lot like the arrangement in Ukulelezaza's books, but that's a credit to the song.
I "looked inside" at Amazon. Wow, tabs for every song. If you're a Ukulele Way student like me, you know from those books that JH gives you tab for a song only if he decides you need it!
I purchased a kindle edition of this book the other day and absolutely love the arrangements, most work equally well for high or Low G. I can highly recommend this book, it's awesome!
I received the book several weeks ago, but due to out-of-town travel, I wasn't able to work on it. I started working on it this week and my initial opinion is that this is the best set of ukulele arrangements I've seen. It's not easy stuff but quite worth the effort for the results. It's not a strum-and-sing book, but if you want to play like an instrumental ukulele virtuoso, then this book will not disappoint.
Mine arrived yesterday. I'm working on Samantha Muir's 'Little Book of Carulli', probably won't get to the J Hill book for a little while - maybe over the holidays.
I bought the book straight away and as much as i love James I'm not in love with the book. This is only because the arrangements are generally just chorded melody. I learn much slower in books and am very good at making my own chorded melodies. Making my own is just easier. Plus my eyesight is not that great and the numbers are so squashed I find them hard to read. Just stating my opinion here as I'm sure we would like all takes on the book.
It's not expensive, so by all means buy it just to support him and Jumpin' Jim
