Thanks for the video. I love that she purchased her first ukulele at 11. I've been educated about the Bruce Wei ukulele customs (incredibly inexpensive but apparently they don't always sound great, which doesn't matter if you are using a pickup). If I were at a ukulele manufacturer, I would be working to sign the young lady to a contract, have her play our ukuleles, and get a custom (mass replicated) model out ASAP. I would have done that the day after her first audition. The ukulele "pros" aren't in the public eye as a whole. As great as Jake Shimabukuro and James Hill are, 21 Pilots have had far more of an impact on (current) kids being interested in ukulele. Grace, with all of the attention she is getting, could be the driver for a lot of ukulele sales.
As a middle school teacher, a singer, and now a ukulele player, Grace's rise to fame has been fascinating for me to watch.
She seems incredibly grounded for a 12-13 year old, and while she has incredible "adult" moments, she is also still a kid. It seems like she has great support at home with a supportive family. From her own description, she sounds a bit like she is on her own at school (small group of friends) which isn't surprising--many of my best "music" students have shared that level of social integration.
I am simply blown away by her songs--I have never had a student in twenty years of teaching (middle school or high school) that has been able to write songs like she does. While the harmonic sequence of her songs seem to be pretty basic (let's be honest...the same is true for many songs), she is able to craft songs with memorable, catchy tunes.
There is no doubt that her "whole package" is part of her appeal (appearance, personality, instrument, her own songs), and it is unlikely she would get the same shot if she were 21 or 35.
I do worry about her speaking voice and singing voice a little bit, as a singer and teacher of voice. The "gravely" parts of her voice are not healthy, and while that sound is part of her appeal, it may not serve her well in the long run. I am hoping that they are working with or seeking a good voice teacher that can help her develop her own style (which is usually not the case) yet avoiding vocal disfunction.
I don't know what her "lasting power" will be, or if she will even choose to pursue music after high school (she still has 5 or 6 years of school before then). But for this period of time, she is bringing joy and encouragement to a lot of people, and if this is "it," six months in the national eye without losing yourself is a pretty good run in and of itself, too.
