Problem singing a section

[rreffner]

In “Desperado” by the Eagles. G to Am to ‘Em. Problem raising tone from G to ‘Em.

 

[Renaissance-Man]

It doesn't have to be a note for note duplication. Otherwise, change the key.

 

[Wiggy]

Sometimes you have to sing (or play) the note that is not on the chord sequence.

Play the chords and sing the "missing" note. It feels good.

This is your impetuous, to learn barre chords.
See https://ukebuddy.com/ukulele-chords/Em-chord for a reference.
The G maj slides up two frets to A maj and you turn it minor, and then you find a higher up the neck Em that works for you.
