Hi, guys! Hope all is well.

The way I understood improvisation with scales: is that you choose the same scale as the root chord being played. For example, if I played the following chords Em, G, D, the root chord is Em and then I should use the Em scale to improvise. Is this accurate? Correct me if I'm wrong, please.

Now, when someone plays the mentioned above group of chords, or when I use an Em backing track, I try to improvise using the Em open scale, but it doesn't feel right; actually the sound is rather wrong and just off!

So, what am I doing wrong?

As always, your opinion is highly appreciated.
