"estar a tono"

Question

what does this phrase mean ?

Answer 1

I'll give these examples

• El discurso del presidente no estuvo a tono

It means that the president didn't make a good speech

• Aún no estoy a tono

I'm not still ready

Answer 2

It's in tune, probably referring to a musical instrument or a voice.

Answer 3

Hola,

En Colombia a veces se dice "estar entonado" para referirse a estar un poco borracho, no caído de la borrachera, pero empezando.

Hope this helps.
