Look at these sentences:
Je ne regarde pas non plus la télé.
I don't watch TV either.
Je n'y vais pas, et toi? -Non, je n'y vais pas non plus.
I'm not going, you? -No, I'm not going either.
Laura ne se lève pas tôt.- Thomas ne se lève pas tôt non plus.
Laura doesn't get up early.- Thomas doesn't get up early either.
When you want to express that someone is not doing something either, you need to use the negative expression ne ... pas non plus.
Note that while ne is always before the verb, pas and non plus can be separated in the sentence, and non plus placed before OR after the object of the verb:
Je ne regarde pas non plus la télé.
I don't watch TV either.
Je ne regarde pas la télé non plus.
I don't watch TV either.
In the case of adverbs, pas and non plus are always separated.
Il ne joue pas souvent au foot, et toi ? -Je n'y joue pas souvent non plus.
He doesn't play football often, and you? - I don't play often either.

Elle ne joue pas de flûte non plus
I thought instruments were ‘joue de la’ (in this case flûte) - is there a reason the ‘la’ has fallen off in this example?

The article is gone due to the negation.
This is true for pretty much everything, not just musical instruments.
"J'ai du lait." -- I've got milk.
"Je n'ai plus de lait." -- I don't have any milk left.
