Riddles Three

Riddle One

All has everything if you know what to see.

It is there in height, both the high and the short,

in rows at the market, where a booth is your key,

or when tiredness stuck and your bed you sought.

Just give me a shout when you identify me.

Riddle Two

Major and minor, a sweet and sour melody.

Strategic and significant, I am something quintessential.

Codex and security makes me totally fundamental.

A gift at majority, it assumes authority

but at the dock you will never find me.

Riddle Three

Essential, breathed in,

flammable, released as waste,

iced, liquid, or gas.
