Picking up from a previous thread:

For classical (tonal) music ... another book ... look-up method was simplified ... (IIRC) just U (for Up), D (for Down) and S (for same) [actually R for Repeat] to identify the note-to-note changes in the melodic line ("Parsons code")
I've come across this on-line melody search, based on the Parsons Code: http://www.musipedia.org/melodic_contour.html

and some other search features described here: http://www.musipedia.org/

Today I heard a 30-min radio programme (BBC Radio 4) "From Dots to Downloads": http://www.bbc.co.uk/iplayer/episode/b00lp15m/From_Dots_to_Downloads/

- (hurry while stocks last) not accessible outside Britain; programme starts ~1 min in.

It was mainly about musician's notebooks (typically from 150+ years ago) of melodies, but included a section (from ~ 11'20") about a code called "abc", invented by a Chris Walshaw, which uses note letters for pitch and numerical codes for length: http://abcnotation.com
designed primarily for folk and traditional tunes of Western European origin (such as English, Irish and Scottish) which can be written on one stave in standard classical notation. However, it has been used for many other types of music

Clicking on "abc tune search" goes here (no pop music): http://abcnotation.com/search.html

- eg to try the example used in that Radio 4 programme, search for "Joshua Gibbons" (two pieces found)
- I tried "Orlando Gibbons" - 24 found, though including five individual parts for "The Silver Swan", etc.

According to that Radio 4 programme, musicians are putting music in various places on line using the abc code, and this search routine is able to find a lot of them.

Also, there's various software available, eg to convert abc-encoded music to normal staff notation.
