"That I might sing it, madam, to a tune."
As time and 'tune' were synonymous, perhaps the poet used the former, which would accord with 'rime.'
"Let's see your song. Why, how now, minion!"
"You do not like it!—No, madam, it is too sharp."
"I see you have a month's mind to them."
A syllable is wanting. Some read moneth, but that is not a Shakespearian form. We might also read 'unto' for 'to' but I prefer 'I see that you'; as I have given it in my Edition.
