Understanding Ukulele Chords by Robert van Renesse:
I think Ukulele World classifies this as an intermediate book. Basically this book explains different chords and how they're used, the roman number system for chords, basic chord shapes on the ukulele, how to derive any chord from the dominant 7th chord shapes, etc. I guess there are other books on essentially this same topic, but this is the one I have. I think it does a good job. If you have this plus a general music theory book, you should do pretty well understanding how to play any chord on the ukulele and why you'd want to.

Highlights:
- three shapes you can use to make major triad chords
- three shapes for minor triad chords
- roman numeral chord notation
- shapes for dominant 7th chords, converting to major, minor, 7ths, 6ths, augmented, diminished, flat 5, etc.
- a 12-bar blues
- 9th, 11th, and 13th chord shapes
- chord substitutions
- tritone substitution
- chord runs
- major and minor chord scales
- creating a chord melody solo
Anyway, all in all this is one of the more useful books I have. -Review by Dan Albro

Famous Solos & Duets for the 'Ukulele , edited & arranged by John King
This book begins with an interesting section on the history of the Ukulele and of early Hawaiian ukulele methods. It then goes on to describe some fairly fancy Hawaiian strum techniques (3 pages on this). Unfortunately, only one song in the book actually uses these. The rest of the songs are played sort of classical style (fingerpicking), but they're good songs and good practice. Comes with a CD, which is handy. -Review by Dan Albro

Jumpin' Jim's Gone Hollywood, compiled & arranged by Jim Beloff
A collection of 32 movie songs, stuff like Singin' in the Rain, Somewhere over the Rainbow, etc. (mostly older movies). GCEA-tuning. Boxed ukulele chords are given at all the chord changes, as in all the Jim Beloff books (well, all two that I have). I haven't actually played these very much, as I suddenly realized after receiving it that I'm not really into this sort of music that much... Seems like a good compilation, though, if you like old movie songs. -Review by Dan Albro

Jumpin' Jim's Ukulele Christmas, c&a by Jim Beloff
30 Christmas songs (well, two are really New Year's songs -- Auld Lang Syne and Jingle Bells, although I guess the latter has since become considered a Christmas song). A nice arrangement, generally, of the standard Christmas songs. Maybe more complex than some other arrangements. One nice feature of this book is that there are optional chord changes marked so that you can choose to change chords constantly or not. Includes a fairly advanced and fancy tabbed-out (well, not really tabbed out, but there's a giant chord diagram over every note) rendition of Dance of the Sugar Plum Fairy, and the rest is just standard chords with melody. Nice book, although as with most of these I wish there were some suggested strumming patterns. -Review by Dan Albro

Fun with the Ukulele by Mel Bay:
My first ukulele book. This just basically has a bunch of folk songs with the chords noted (not boxed, but the chords are introduced gradually with one picture in the book of each chord). Not a lot of depth, but it's fine for a first book, I guess. Oddly, it has a list of many movable chord forms in the back, but not of the open chord forms. I guess you can think of the open chords as bar chords with an implied bar at the nut, but a beginner is unlikely to just know that without it being spelled out somewhere... -Review by Dan Albro

The Cat's Meow : Ukulele Favorites from the Roaring Twenties,
compiled by Ian Whitcomb:
Some nice twenties songs. Some of them are featured in the movie Cat's Meow . There are three things I particularly like about this book: (1) it has a CD in the back, (2) the chords are given in boxes at each chord change, and (3) each song has the original front and (sometimes) back cover art from the original sheet music. That said, I wish there were suggested strumming patterns, and I haven't actually played that much of the music in here because I don't actually know these songs (I should listen to the CD, I guess). -Review by Dan Albro

Mel Bay presents Fun with Strums-Ukulele, by Bill Bay:
I like this book better than Fun with the Ukulele, mostly because of the strums. It contains 29 different strumming patterns, I believe, along with 29 different songs to illustrate them. The chords are not given in boxes at each change, though, just the letters (although there are pages in there with the chords laid out on them). My main critique of this book is that it would be nice to have a CD with it... Anyway, a nice book for beginners, although probably not a good only book. -Review by Dan Albro

Happy Time Ukulele Method and Song Book by Buddy Griffin:
I was a little disappointed by this book, but only because I thought from the description at Ukulele World that it covered more than it really did. It's essentially the same thing as the Mel Bay Fun with the Ukulele, except that it does have a lot more songs and the chord pictures are given with each song (but not inline). It does also have a little section at the end that tells you how to change strings and the basics of reading music. I would probably recommend this over "Fun with the Ukulele" as a book for absolute beginners, but if you've already gone through a different one, there's probably not too much here for you. From the descriptions at ukeland.com, there are probably better beginner books out there. -Review by Dan Albro

DVDs
The Complete Ukulele Course!, by Ralph Shaw:
I'm not sure I'd call this a complete course, but it is quite nice, anyway. Ralph Shaw is quite good, and shows you a plethora of strumming techniques and some things to do with chords (ornament notes). There are only three songs, but a lot is covered with those three, the final song of which is a melody chord song. Includes the Formby split stroke, tremolo, strokes for standard, waltz and jig time, etc. -Review by Dan Albro

Ukulele for Kids, volumes 1 & 2, by Marcie Marxer:
These are fun videos. Basically there's a lady with a giant talking, ukulele-playing dog, and they show kids how to tune, hold, and strum the ukulele. The course covers a few basic strumming patterns and maybe 10 chords. My 6-year old likes the videos (well, 7-year-old now, but he hasn't watched the video since he was 6), especially the dog, although I can't get him to practice much. -Review by Dan Albro
