As others have said, the precepts here are mostly related to making sure that the mediator has a clear and unimpeded mind. I find that meditation is, for most, far easier when one eats little and avoids things that distract the mind; music,singing, dancing, and other things are not immoral, but they can stir up the mind and keep it from growing calm.
Unless you're on a retreat, or plan to really devote yourself to meditation, it is not necessary to take these precepts. Only the five precepts are necessary for a lay person. However, if you are interested in deepening your concentration, it may be worth checking out.
Gain and loss, status and disgrace,
censure and praise, pleasure and pain:
these conditions among human beings are inconstant,
impermanent, subject to change.
Knowing this, the wise person, mindful,
ponders these changing conditions.
Desirable things don’t charm the mind,
undesirable ones bring no resistance.
His welcoming and rebelling are scattered,
gone to their end,
do not exist.
