A number of great suggestions here.

When my son was learning trumpet many years ago, his teacher at first had him play - at tempo and on the first beat of every measure - the root note of the chord. She then had him go in and actually play the proper first note (only) on the first beat.

After that, she'd have him find a note in the measure that he could identify, reach and play and add that to the first note. All of this was up to tempo.

It served him well during live performances - especially at first because he never fell behind the rest of the band; trying to catch up to notes he'd missed.

He was just a pup then, but it helped his confidence a lot because it meant he never hit a bad note.

I'm a fingerpicker trying to learn to play lead and I'm finding myself using that very method. Up to tempo. I actually finish the song instead of getting halfway in, quitting, starting again, etc.

Apologies for the long winded answer.
