Note 9 — INTRODUCTION.
Reading edition
In the classical work of Sahagun, the author describes the ancient poet: "The worthy singer has a clear mind and a strong memory. He composes songs himself and learns those of others, and is always ready to impart either to the fellows of his craft. He sings with a well-trained voice, and is careful to practice in private before he appears before the public. The unworthy singer, on the other hand, is ignorant and indolent. What he learns he will not communicate to others. His voice is hoarse and untrained, and he is at once envious and boastful."9
