All songs can be written as a series of symbols referencing their changes in tone. I will be using a variation of the Parsons Code. Specifically, the first note of each song is denoted as "$*$", and every following symbol describes whether the pitch goes up ($\land$), down ($\lor$), or stays the same ($-$). For example, "Twinkle, Twinkle" would begin as such:
$\ * \ \ - \ \ \ \land \ \ \ - \ \ \land \ - \ \ \ \lor \ \ \ \ \ \ \lor\ \ \ - \ \lor \ \ - \ \ \ \ \lor \ \ \ \ - \ \ \ \ \lor$
Twinkle, $\ \ \ $Twinkle $\ \ \ $Little $\ \ \ $Star. $\ \ $How $\ \ \ $I$\ \ \ $Wonder$\ \ $What$\ \ $You$\ \ $Are.
Using this information, determine the following songs, and the common theme that links them.
-
$*\land\land\lor\land\land\lor\lor\lor\land\land\lor\lor\land\lor\land\lor\lor\land\land\lor\lor\lor\lor\land\land\lor\lor\land \ \lor$
-
$*\land\land------\lor\land\land------\lor\land\land-------- \ \lor$
-
$*--\land\land\lor--\land\land\lor-\lor-\lor-\lor---\land\land\lor--\land\land\land\land\lor\lor\lor\lor \ \lor$
and, by popular demand:
-
$*\lor\lor\land\land--\lor--\land\land-\lor\lor\lor\land\land---\lor-\land\lor \ \lor$
Hint:
The first song was released in 1961, yet is still well known.
