Upgraded ABC search

Upgraded ABC search

OK, I have made some fairly significant changes to the http://abctunesearch.com

I have added more tune data (10200 tunes so far) from multiple sources, including thesession, O'Neill's, and the Reavy collection. And it shows you the source of each tune match.

The "tune types" are now groupings, so it will search reels, hornpipes, and barn dances at the same time, and jigs, slip jigs, and slides at the same time, etc.

And most significantly, I put in the "contour search" feature. If you search for a snippet of ABC, and it doesn't return the result you were looking for, you can select the "contour search" button, and tell it the "root note" of the ABC that you input. It will then generate a contour map, and search across the database for that contour, regardless of key! It works pretty well! (But it can also return a lot of false matches, of course). That feature really comes in handy in cases where my data has a tune in a different key than you are searching for it in...

It's a good idea to read the Help section before using it the first time, because it isn't necessarily fully intuitive.

Anyway, let me know what you think...

Re: Upgraded ABC search

Key doesn't matter in the contour search. Just the root note.

Re: Upgraded ABC search

Going to run out of superlatives soon, Reverend ... ;-)

But surely, to get the best contour match, you would need knowledge of the mode in addition to the key, or are you suggesting that for a tune in A mixolydian, the root note should be entered as D ?

Don't forget Roche's... Yeah, I know, making more work for you... ;-)

Re: Upgraded ABC search

Rick, the contour search works by translating the tune down to a fictional "base key", and it converts it down a certain amount based on the root note of the key. It then checks it against a database of all the tunes that have gone though the same translation. So don't think of it as a musical transposition, think of it as a numerical one...

Re: Upgraded ABC search

I suggested over on another thread that you call this the "Rev Counter" :)

Re: Upgraded ABC search

abctunesearch.com now searches data from thesession.org, O'Neill's 1850, and O'Neill's 1001 (which have some duplicates, but different transcriptions), the Reavy collection, and Henrik Norbeck's transcriptions.

It also gives you the ability to search just one of those archives, or all of them.

Combine that with the contour search, and it's pretty darn powerful. Alas, it still can't find lonannas' slide, though... :-/

Just FYI, this latest round of upgrades are probably the last for a while.

Hope that means you have found gainful employment again :-)

Well, not *exactly* gainfully employed yet, but things are looking potentially positive, thanks! :-)
