Think quietly about me touring the States (4)
I believe the answer is:
muse
'think quietly' is the definition.
'muse' can be an answer for 'think' (to muse on something is to think about it). I am unsure of the 'quietly' bit.
'me touring the states' is the wordplay.
'touring' is an insertion indicator (tour can mean to go around).
'the states' becomes 'US' (abbreviation for the United States).
'me' enclosing 'us' is 'MUSE'.
'about' is the link.
Can you help me to learn more?
(Other definitions for muse that I've seen before include "Ponder in meditative way" , "Ponder or meditate" , "Contemplation" , "Cogitate" , "Goddess; rock group" .)
