“Therefore I would give this as a caveat, or caution, to any, who do attempt to exercise their fancies in such matters of Invention, that they observe times, and seasons, and never force themselves to anything, when they perceive an indisposition; but wait for a fitter, and more hopeful season, for what comes most compleatly, comes most familiarly, naturally, and easily, without pumping for, as we use to say. “Strive therefore to be in a good, cheerful, and pleasant humour always when you would compose or invent, and then, such will your productions be; or, to say better, chuse for your time of Study, and Invention, if you may, that time wherein you are so disposed, as I have declared. And doubtless, as it is in the study and productions of Music, so must it needs be in all other studies, where the use and exercise of fancy is requirable. “I will therefore, take a little more pains than ordinary, to give such directions, as you shall no ways wrong, or injure my Mistress, but do her all the right you can, according to her true deserts. “First, therefore, observe to play _soft_, and _loud_, as you see it marked quite through the Lesson. “Secondly, use _that Grace_, which I call the _Sting_, where you see it set, and the _Spinger_ after it. “And then, in the last four strains, observe the _Slides_, and _Slurs_, and you cannot fail to know my _Mistress's Humour_, provided you keep _true time_, which you must be extremely careful to do in all lessons: FOR TIME IS THE ONE HALF OF MUSIC. “And now, I hope I shall not be very hard put to it, to obtain my pardon for all this trouble I have thus put you to, in the exercise of your patience; especially from those, who are so ingenious and good-natured, as to prize, and value, such singular and choice endowments, as I have here made mention of in so absolute and compleat a subject.” MY MISTRESS OR MRS. MACE. [Illustration: musical score.] THOMAS MACE. There is no prettier story in the history of Music than this; and what a loving, loveable, happy creature must he have been who could thus in his old age have related it! CHAPTER CXCV. ANOTHER LESSON WITH THE STORY AND MANNER OF ITS PRODUCTION. _Οὐδεὶς ἐρεῖ ποθ᾽, ὡς ὑπόβλητον λόγον, ———ἔλεξας, ἀλλὰ τῆς σαυτῦ φρενός._ SOPHOCLES. Master Mace has another lesson which he calls Hab-Nab; it “has neither fugue, nor very good form,” he says, “yet a humour, although none of the best;” and his “story of the manner and occasion of Hab-Nab's production,” affords a remarkable counterpart to that of his favourite lesson.
