Use the Envelope Tool
Click the top edge of your audio wave where you want the fade to begin
Watch the shape of the wave!You dont want to pinch

24. Editing spoken word
Mute your intro music
Import Ode Urn.wav
Here is the text as it should be read:
Fair youth, beneath the trees, thou canst not leaveThy song, nor ever can those trees be bare; Bold Lover, never, never canst thou kiss, Though winning near the goal;yet, do not grieve; She cannot fade, though thou hast not thy bliss
Use Audacity to delete unwanted parts to create a good read of this stanza
25. Editing spoken word
Fair youth, beneath the trees, thou canst not leaveThy song, nor ever can those trees be bare; Bold Lover, never, never canst thou kiss, Though winning near the goal;yet, do not grieve; She cannot fade, though thou hast not thy bliss
Using the Selection Tool highlight unwanted portions of the audio
Zoom In if you are unsure about what to select
Push the delete key
Dont forget, you can undo if you make a mistake
When you are done, select the entire piece, and copy and paste another stanza at the end of the reading

`Twasbrillig, and the slithytoves;Did gyre and gimble in the wabe:All mimsy were the borogoves,And the momerathsoutgrabe
"Beware the Jabberwock, my son!The jaws that bite, the claws that catch!Beware the Jubjub bird, and shunThe frumiousBandersnatch!"
He took his vorpal sword in hand:Long time the manxome foe he sought --So rested he by the Tumtum tree,And stood awhile in thought.
And, as in uffish thought he stood,The Jabberwock, with eyes of flame,Came whiffling through the tulgey wood,And burbled as it came!
One, two! One, two! And through and throughThe vorpal blade went snicker-snack!He left it dead, and with its headHe went galumphing back.
"And, has thou slain the Jabberwock?Come to my arms, my beamish boy!O frabjous day! Callooh! Callay!He chortled in his joy.
