As far as well written songs go, I’d have to say Elton John’s Goodbye Yellow Brick Road ranks at least in my top 10. The soaring melody and odd, but brilliant chord changes makes for a very interesting and memorable piece.
This tab is in D – the lowest you can go and still play the melody with a high-g – and it uses the whole range of the ‘ukulele. There’s nothing remarkable about the picking because it’s just a plain-jane version of the melody. The chords, however, will be a fun challenge for intermediate uke players since there are lots of them and many that are out of key.
If you want to try and arrange it as a solo ‘ukulele piece with chords and melody woven together, I’d recommend learning each part separately. Sing or hum the tune and strum the chords until they are comfortable and then switch to picking out the single-note melody. This will force you to become familiar with each facet of the song before trying to put it together. Jumping to the full arrangement too fast is often the cause of unsteady timing and a less satisfying sound. So take your time and learn each bit individually.
