Do (dō), n. (Mus.) A syllable attached to the first tone of the major diatonic scale for the purpose of solmization, or solfeggio. It is the first of the seven syllables used by the Italians as manes of musical tones, and replaced, for the sake of euphony, the syllable Ut, applied to the note C. In England and America the same syllables are used by many as a scale pattern, while the tones in respect to absolute pitch are named from the first seven letters of the alphabet.

Do (d?), v. t. or auxiliary. [imp. Did (dĭd); p. p. Done (ducr/n); p. pr. & vb. n. Doing (d?"ĭng). This verb, when transitive, is formed in the indicative, present tense, thus: I do, thou doest (d?"ĕst) or dost (dŭst), he does (dŭz), doeth (d?"ĕth), or doth (dŭth); when auxiliary, the second person is, thou dost. As an independent verb, dost is obsolete or rare, except in poetry. "What dost thou in this world?" Milton. The form doeth is a verb unlimited, doth, formerly so used, now being the auxiliary form. The second pers, sing., imperfect tense, is didst (dĭdst), formerly didest (dĭd"ĕst).] [AS. dōn; akin to D. doen, OS. duan, OHG. tuon, G. thun, Lith. deti, OSlav. dēti, OIr. dénim I do, Gr. tiqe`nai to put, Skr. dhā, and to E. suffix -dom, and prob. to L. facere to do, E. fact, and perh. to L. -dere in some compounds, as addere to add, credere to trust. √65.

(b) They are often used in emphatic construction. "You don't say so, Mr. Jobson. -- but I do say so." Sir W. Scott. "I did love him, but scorn him now." Latham. (c) In negative and interrogative constructions, do and did are in common use. I do not wish to see them; what do you think? Did Cæsar cross the Tiber? He did not. "Do you love me?" Shak. (d) Do, as an auxiliary, is supposed to have been first used before imperatives. It expresses entreaty or earnest request; as, do help me. In the imperative mood, but not in the indicative, it may be used with the verb to be; as, do be quiet. Do, did, and done often stand as a general substitute or representative verb, and thus save the repetition of the principal verb. "To live and die is all we have to do." Denham. In the case of do and did as auxiliaries, the sense may be completed by the infinitive (without to) of the verb represented. "When beauty lived and died as flowers do now." Shak. "I . . . chose my wife as she did her wedding gown." Goldsmith.
