We will now determine whether it is proper that children should be taught to sing, and play upon any instrument, which we have before made a matter of doubt. Now, it is well known that it makes a great deal of difference when you would qualify any one in any art, for the person himself to learn the practical part of it; for it is a thing very difficult, if not impossible, for a man to be a good judge of what he himself cannot do. It is also very necessary that children should have some employment which will amuse them; for which reason the rattle of Archytas seems well contrived, which they give children to play with, to prevent their breaking those things which are about the house; for at their age they cannot sit still: this therefore is well adapted to infants, as instruction ought to be their rattle as they grow up; hence it is evident that they should be so taught music as to be able to practise it. Nor is it difficult to say what is becoming or unbecoming of their age, or to answer the objections which some make to this employment as mean and low. In the first place, it is necessary for them to practise, that they may be judges of the art: for which reason this should be done when they are young; but when they are grown older the practical part may be dropped; while they will still continue judges of what is excellent in the art, and take a proper pleasure therein, from the knowledge they acquired of it in their youth. As to the censure which some persons throw upon music, as something mean and low, it is not difficult to answer that, if we will but consider how far we propose those who are to be educated so as to become good citizens should be instructed in this art, [1341a] and what music and what rhythms they should be acquainted with; and also what instruments they should play upon; for in these there is probably a difference. Such then is the proper answer to that censure: for it must be admitted, that in some cases nothing can prevent music being attended, to a certain degree, with the bad effects which are ascribed to it; it is therefore clear that the learning of it should never prevent the business of riper years; nor render the body effeminate, and unfit for the business of war or the state; but it should be practised by the young, judged of by the old. That children may learn music properly, it is necessary that they should not be employed in those parts of it which are the objects of dispute between the masters in that science; nor should they perform such pieces as are wondered at from the difficulty of their execution; and which, from being first exhibited in the public games, are now become a part of education; but let them learn so much of it as to be able to receive proper pleasure from excellent music and rhythms; and not that only which music must make all animals feel, and also slaves and boys, but more. It is therefore plain what instruments they should
