If you are not afraid to share your own materials on Youtube, Soundcloud, Spotify and the like then there is no reason to be afraid to share your music or an elaborated idea on Jamujam. Jamujam.com does not differ significantly in this respect from the mentioned networks, which you may already use. The fear that someone will officially pretend to be the author of your shared song a month later is more or less unnecessary. The assumption is that as the author of the song, you are undoubtedly the first on earth to upload the song somewhere, whether on a network as a post or on a private cloud storage, as a stored file without the possibility of antedating.
There is a greater risk that someone will “steal” a song from you when you play it on a guitar somewhere in the pub, without recordings or original data stored on a Google drive, for example, which would later prove that the song is really your original work. In this case, it is difficult to prove anything. Be careful here.
TIP: If you want to protect your works as their author, it is wise to use the mentioned online options. Once you upload your song or at least a few bars or an unfinished version to the cloud repository, which in a way are also social networks, the uploaded file will display the upload date without the option of antedating – which is crucial. If you are the author of a given song, of course you are the first to own the very first versions and data of this song. This is, of course, an ace up your sleeve, if anyone tries to claim later that he or she is the original author of the song...
In the case of methods of copyright protection, the classic method of notifying the work to the Copyright Protection Society (CPS), which will get you into the records of the collective administrator, cannot be neglected. By registering a song in CPS, the song becomes registered and CPS collects fees for its use. This method is more suitable for announcing an actually finished work with all the bits of it that will be played on radio stations, etc. Thanks to Internet services, this method is no longer so widely used to prove authorship.
At Jamujam.com, there is the possibility of private or even invisible “jams” for bands or established music groups. This means that no one else will be at the birth of your new hit if you don't want to. This way you can create your songs just like in a private rehearsal room.
If a song becomes a hit that has the potential to make money and breakthrough in the charts, it's the same with a song copyright here as if your song was created by your band in a rehearsal room or studio. All that matters is how you agreed the copyrights within the band, regardless of whether your hit is created in the rehearsal room or in the Jamujam.com virtual creative room.
To avoid possible disputes after the success of your band and if you are really serious about your work, it is necessary for all members to make a special sitting on this issue, agree on something and, ideally, put such an agreement on paper.
From the point of view of law, all co-authors decide on the use of each co-author's work unanimously, i.e. together, however, the amount of their co-author's contributions is then decisive in the case of the distribution of remuneration for use.
This can, of course, happen.
The open public jams on Jamujam are intended for entertainment. For inspiration, for training and for musicians to show off, to compete who can compose a better melody, etc., without any higher goal or ambition, such as jamming somewhere in a club. You probably don't care if someone shoots it, for example...
However, once you feel that a lucrative composition with commercial potential is emerging in a given jam, it is up to each individual to decide how to arrange their eventual co-creation with the jam founder.
In general, the main author of a composition created in a given jam is the one who created the jam. Alternatively, the one who recorded the first song in the jam with the prospect of expanding it in the future ... However, it is common for songs to have more authors or co-authors.
The joint creation of a finished composition has basically three features and from a legal point of view it cannot always be called “co-authorship”.
Of course, when you make up lyrics to instrumental music, this song will have the author of music author and you as the author of the lyrics. If there is a potential chance that you will want to claim copyright for a song, it is important to have clear evidence that the lyrics are your work and were created before the song was officially published. Ideally, you should save the song to Google Drive, for example, in PDF format before singing the lyrics. This was once done by keeping texts or compositions written in notes in notarial boxes with the date and time of insertion. Today's cloud storage, where it is not possible to change the storage date of a file that is automatically overwritten when uploaded, performs a similar function today. Or send the lyrics to someone by email. It's basically the same thing, only in a simpler form.
For works that feel commercial potential, it is up to each contributor to the work to agree on the terms with the songwriter. Of course, if you record rhythms or some melodies into the finished song, it is of course not a co-authorship or a joint author's work, as when you text the song. However, you have the right to be listed for this song, at least to this extent, as a solo guitarist or as a drummer/keyboardist, etc., and you are entitled to some royalties in the event of the commercial success of the composition thus modified.
How you exercise this right and agree on it then differs on an individual basis. Jamujam.com provides you with a platform for online music production and instructions on how to provide proof of being involved in making a song, if you experience a dispute over co-authorship or contribution to the creation of the song. These disputes are resolved in accordance with the copyright law of the country. Jamujam.com has no obligation to engage in such disputes. At the same time, however, it can help voluntarily within the possibilities it has.
