Subject: Re: improvement

Yes, this would not be a problem. The question is whether it would really be better - there is a tradeoff between robustness against errors in the user input and search accuracy. Especially when users whistle or sing the query, the intervals in the query are not always correct, but the rough Parsons code makes those errors irrelevant. On the other hand, queries need to be longer for recognizing a melody than they would have to be with a finer countour.

There is a site where you can experiment with searching both for the very rough Parsons Code-like contour and for exact intervals: http://themefinder.org

I find that the robustness and also the ease of entering Parsons code outweigh the advantages of exact interval sequences, mainly because the number of notes you need to encode as Parsons Code for finding a melody among 30,000 melodies is not that large (about 8-15, depending on the melody).

I put some pointers to other possible improvements on the "About Musipedia" page (click in the menu to the left).

Cheers,

Rainer

Could a system similar to musipedia be implemented which tells how much higher up or farther down the next note is?

Hello,

from now on, you can very simply jump to melodies similar to a given Parsons Code, simply by entering something like:

http://www.musipedia.org/contour/ RRRRDDUDDUDDDDD

Of course, you can write whatever Parsons Code you want after /contour/.
This example URL should lead to Cat Stevens' "Moonshadow".

German-speaking people may write instead:

http://www.musipedia.org/kontur/ RRRRDDUDDUDDDDD

to see the search result page in German.

Enjoy!

Rainer

You must login to post a message to this conference.

Add a bit of sheet music, along with a MIDI file, simply by entering note names in Lilypond syntax between the [L] and [/L] tags.
For example, you can try what happens if you enter: [l]g'4 g'4 d''4 d''4 e''4 e''4 d''2[/l] (use the Preview function if you don't actually want to post this).
You can create these lists of note names by clicking on piano keys here.

If you just want to sing, whistle, or play a melody so that other forum visitors can hear it, follow these steps:

1. Record your audio here.
2. You should notice a 32-character hash code, something like: 2a40281c5001c5a7d8c9f57fcdeccfaf
3. copy this hash code and paste it into a forum post, enclosed in the audio tags, for example: [audio]2a40281c5001c5a7d8c9f57fcdeccfaf[/audio]

If the original question in a thread is solved, please mark it as solved using the "solved" icon (or by just typing [solved] into your post). This makes life easier for people who are willing to identify melodies, since unsolved problems are easier to spot that way. If a problem turns out to not be solved after all, just write [/solved] in a new post, and the thread will be labeled accordingly.
