Hello, I am new to the ukulele and I have learned to tune it but the first string which is supposed to be in the chord of A does not make that sound I use an electric tuner and it says that it is in A, but from the videos I have seen it does not sound the same, it sounds like just a normal piece of string that is vibrating, and I know since its a new instrument it will take time for the strings to be correct, but all the other strings sound somewhat nice, thank you
