Any other recommendations on tuning for a beginner?]
Okay. If the question is for a beginner, literally almost any tuner will work.
If you're looking for THE MOST ACCURATE you're going to need to look at the tuners by TC Electronics or Peterson (both clip-on tuners). Both have a ridiculous sensitivity to pitch.
A few years ago, I watched a video by Cool Cat Ukes (Simon Taylor) who compared tuners using a pitch generator. I replicated his study, and came to the same conclusions...of the tuners I had in the house, the D'Addario were the most sensitive. My ears can't hear that small of a difference. I do not have the Peterson or TC Electronics tuners, and my YouTube channel is going to have to start paying a whole lot more if I am going to buy one (I'd rather buy ukuleles to review).
Some tuning tricks:
1) Get used to tuning "grossly" at first. In other words, get close by ear, and then fine tune after that.
2) String teachers will tell you to always tune up, partially because the strings are going to loosen regardless of what you do. So why facilitate the loosening by tuning down. If you're above the pitch, go under and tune up.
3) And there are going to be times to ignore #2, such as when you are tuning 30 ukuleles for students. Time is time.
4) If you ever hear someone is out of tune, there is a nice way to suggest that they tune, "Would you like to use my tuner?" This is similar to, "Would you like to have some gum?" (bad breath is just as bad as an out of tune ukulele).
5) Always check to make sure you're turning the peg for the right string. We've all done it. Some have broken strings accidentally.
6) When a ukulele is new, or strings are new, you're going to have to tune them for a while. Most modern tuners don't "slip" (although there are still friction tuners that do and need to be tightened).
7) when you change strings, just make sure every screw is tightened, too, as part of the process.
How are those for tips?
