Scan the lines provided from Sonnet 73. Mark the syllables, separate the feet with short vertical lines, and indicate the rhyme scheme. That time...

It's confusing, yes, to mark up a passage of verse with
all the signs and symbols.  I will scan the first few lines for you and give the rhyme
scheme of these line, and then you can finish it!  Once you understand the task/tools, I
think you will find it easier. and when you have seen my scansion of the text, if you
want further explanation, follow the link below to "iambic pentameter" and scroll down
to the "simple example" given there.

The fact that the
verse is written in iambic pentameter is the key.  The poetic rhythm of this is based
upon our heartbeat and, in stress goes something like this: da
DUM, da
DUM, da
DUM, da
DUM, etc.  The DUM is in all
caps and bolded because this is the syallable of each foot that is stressed.  There
should be five feet, each foot comprised of two
syllables (one unstressed and
one  stressed), in a line of iambic pentameter
verse.

Here's the way I would begin to scan the lines of
verse you provide:

readability="7">

That time
-- of year --
thou mayst-- in
me -- be
hold

When
yel -- low leaves --
or none --
or few -- do
hang

Please
note that I can't create the symbols easily on my computer so, instead of a vertical
line between the feet, I have used a dash, and instead of the forward slash placed above
the stressed syllables, I have made the syllable bold.  Instead of the little "u" or
breve mark, I have italicized the unstressed syllables.  You can see, if you consult the
imabic pentameter link below, how to create the slash and the breve
above your stressed and unstressed syllables.  It will also
show you how to separarte you feet.

As for rhyme scheme,
sonnets follow a particular rule.  Begin with the last word of the first line.   This
will be your A word.  Look at the second line.  The last
world should not rhyme with word A, so call this word
B.  In line three you have a rhyme with line one, so this
is A again, and in line four,
B.  Like
this:

...behold  
A

...hang  
B

...cold  
A

...sang  
B

Hope this
helps!
