1) ORIGINS
The earliest form of musical notation can be found in a cuneiform tablet that was created at Nippur, in Sumer (today's Iraq) in about 2000 BC

2) THE MUSIC STAFF
Guido of Arezzo (c. 990-1050), an Italian monk, developed the idea of a musical staff to house the different pitches.

3) MUSIC NOTATION
Ancient Greek musical notation was in use until approximately the 4th century AD; several complete compositions (and fragments) using this notation survive.

4) DEFINITION
An orchestral score shows exactly what all the instruments of the orchestra play. For a large orchestra with many different instruments, the page must be very tall. 

5) VARIATIONS
A miniature score (or pocket score) is like an orchestral score but much smaller, thus not big enough to conduct from because the print will be too small.

6) LOGIC
In an orchestral score, the order in which the instrumental lines are usually printed is woodwinds, brass, percussion, and strings.

7) PAPER
Printing had a big impact on the music industry, as sheet music was being hand written by only those with the knowledge, who could afford the material.

8) DURATION
According to the 2019 Guinness World Records, the longest officially released song was “The Rise and Fall of Bossanova,” by PC III, lasting an amazing 13 hours, 23 minutes, and 32 seconds. In Pop music, the longest recorded song is “Apparente Libertà,” by Giancarlo Ferrari, which is 76 minutes, 44 seconds long.
