We can see most requested chord progressions by looking through our log files, so there's no need to ask about it explicitly. We do our best to make the project suitable for as many musicians as possible. However due to limitiations of our resouces the process of transcribing new licks sometimes takes a while.

Before processing your request we have to validate your input to convert chords you use to BopLand standard. After that we extract data from the database. In total it requires a fraction of second, however if there are many users making requests at the same time there can appear a certain delay up to several seconds.

We stated that there are no casual licks at BopLand.org. Every pattern is melodious and harmonically accurate. To match these rules, we have to thoroughly examine the phrases submitted to the database. Even the greats of jazz improvisation sometimes made mistakes. We accept only those licks irreproachable from any point of view.

There are no casual licks in the database. Before a lick can be found by an external user it should be verified by professional musicians engaged in the project. Usually verification procedure takes several days after the lick was submitted. If a long time passes and the lick is still not in the database, the most probable reason is that it was deleted due to melodic errors or placed in the database in a slightly corrected form. All these actions are reported to the user if he specified his e-mail while adding the lick.

We readily accept licks transcribed from famous musician solos. Although being improvisational these patterns are not spontaneous but obey very strict rules rooted in the J.S. Bach epoch. If you know the rules you can try to add your lick to the database. If not, then the best way to contribute is to transcribe a solo piece.

Start with the following example: 4/4 | Fm7b5 ab+8 f gb ab cb eb gb bb | Bb7 ab f gb ab db cb gb d | Ebm7 f fb eb4 r2 | Insert this string into the text area at new lick page, press "Preview" button and analyze the results. Feel free to experiment.

Yes. Once played by a musician, a good jazz lick was replayed thousand of times by many others, so it is practically impossible to say this pattern was first played by Clifford Brown, Charlie Parker, Sonny Rollins, Dizzy Gilespie, or Lester Young. All these licks became the property of improvising musicians and the authorship of all licks in the database is collective.
