Is it possible that it's nerves? I worked with a guitarist who's timing was impeccable until the dreaded 'record' button was hit and then his hands turned into pretzels. The bigger the studio the badder the timing. So maybe techniques to get her relaxed?
Sometimes it can be a way of getting more time and attention too.
Definitely needs to get sorted though and rigorous practice a la Standen technique are required.
We actually record every single artist to a click track. We use the PT internal click. If they can't get the timing right away, we burn them a copy of whatever scratch tracks we have, with the clik and let them take it home and practice. Next session is almost always right on.
A click track usually only works for artists who already have good time and studio experience. For
those who need time help I make midi drum tracks
with the right feel for what they're doing-sometimes I even program a bass track also depending on the style and needs of the track.
It's work but it pays off tremendously in the final product.
Cluck Fick tracks. Or is that clack ^#$% tricks?
I learned long ago, two people constitute a groove. Very rare for a solo artist to really groove- I think like Ravi Shankar said, music is the space between two souls.
I guess I'm a ritardando for not tolerating click tracks- look what they did to Keith Moon! That's some weak drumming on "Baba O'Riley", especially for Keith Moon! So the guy was human!
Jam along on a scratch track, or if it's good keep it! Is it good?
Teach them to tap their foot then, for beginner guitar players its good to help them find a struming pattern that sotra works with the tapping foot in 4/4. Such as:
Down on beat 1
Down on beat 2
Up on the & of beat 2
Up on the & of beat 3
Down on beat 4
Up on the & of beat 4
Don't confuse them with counting yet, just help them find beat 1.
Make them a click track where beat 1 is accented. This is a very good exercise for beginner guitar players. "Every Rose has its Thorn" by Poision is perfect to learn to play and sing with this strumming pattern. Almost every single lyrical accent falls on a strum. In fact you will be amazed at how many vocal rhythms go perfectly with this struming pattern.
