Position Of Strokes On The Basis Of Vowels

 We usually take notes in shorthand in a notepad having ruled sheets because while writing shorthand, the same stroke will have a different pronunciation depending on whether we write it above the line, on the line or through the line. 

Sound	Placing	Examples
Long aa, Short a	Above line	Palm, Calm, Pa, Said, cat, family
Long aw, Short o	Above line	Poem, Offer, Talk, Foster
Long ee, short i	Through the line	Eat, tea, bit,tick
Long oo, short oo	Through the line	Tools, boot, put, took
