Systems and methods for facilitating transactions of musical stems between users of an online gaming platform and mixing of the musical stems

A method for facilitating transactions of musical stems between users of an online gaming platform and mixing of the musical stems, the users including a first user, the method comprising:

• electronically storing information, wherein the information includes one or more tracks including a first track, wherein the first track includes a first arrangement of a set of musical elements, wherein the first track can be played back to generate an audible sound that represents the first arrangement, wherein the first track has a first progress length spanning a first number of beats, wherein the first track includes four stems, wherein individual ones of the four stems have the first progress length, wherein individual ones of the four stems include a subset of the set of musical elements such that a simultaneous combination of all of the individual ones of the four subsets equals the set of musical elements, wherein at least one of the four stems includes one or more pitched musical elements in a first key when played back at a first tempo;
• and
• transmitting a purchase request that indicates the first user offers to purchase a right to use a given stem, wherein the given stem includes a given arrangement of one or more given musical elements in a given key when played back at a given tempo;
• receiving a notification of assignment of the right to use the given stem to the first user, wherein the assignment is part of a transaction that has been recorded on a decentralized database that stores a registry of assets and transactions, wherein the decentralized database represents a blockchain;
• obtaining the given stem;
• generating a second arrangement of musical elements, wherein the second arrangement includes the given stem and the at least one of the four stems included in the first track, wherein generation of the second arrangement includes:
• (i) modifying the given stem into a modified stem such that the given arrangement has a modified key when played back at the first tempo, wherein the modified key is within 10 cents of the first key;
• (ii) combining the at least one of the four stems included in the first track and the modified stem such that the second arrangement has the first progress length;
• and
• playing back the second arrangement of musical elements to generate a second audible sound that represents the second arrangement.

A system configured for facilitating transactions of musical tracks between users of an online gaming platform and mixing of stems included in the musical tracks, the users including a first user, the system comprising:

• electronic storage configured to electronically store information, wherein the information includes a set of tracks including a first track, wherein the first track includes a first arrangement of a set of musical elements, wherein the first track can be played back to generate an audible sound that represents the first arrangement, wherein the first track has a first progress length spanning a first number of beats, wherein the first track includes four stems, wherein individual ones of the four stems have the first progress length, wherein individual ones of the four stems include a subset of the set of musical elements such that a simultaneous combination of all of the individual ones of the four subsets equals the set of musical elements, wherein at least one of the four stems includes one or more pitched musical elements in a first key when played back at a first tempo;
• and
• one or more hardware processors configured by machine-readable instructions to:
• transmit a purchase request that indicates the first user offers to purchase a right to use a given track that includes four stems, wherein the given track includes a given arrangement of one or more given musical elements in a given key when played back at a given tempo;
• receive a notification of assignment of the right to use the given track to the first user, wherein the assignment is part of a transaction that has been recorded on a decentralized database that stores a registry of assets and transactions, wherein the decentralized database represents a blockchain;
• obtain the given track;
• generate a set of arrangements of musical elements, wherein the set of arrangements includes a given arrangement, wherein the given arrangement includes at least one stem from the given track and at least one stem selected from the set of tracks, wherein generation of an individual arrangement in the set of arrangements includes:
• (i) automatically selecting a melody stem, wherein the melody stem provides a master key and a master tempo;
• (ii) automatically selecting up to three additional stems from the set of tracks and the given track, such that the up to three additional stems have up to one harmony stem, up to one bass stem, and up to one drum stem;
• (iii) modifying the up to three additional stems into modified stems such that the individual arrangement is within 10 cents of the master key;
• and
• (iv) combining the melody stem and the up to three additional stems;
• and
• playback, to the first user, the set of arrangements including the individual arrangement to generate audible sound that represents the set of arrangements, wherein the generation of the set of arrangements and the playback of the set of arrangements occurs automatically without requiring user input from the first user.
