# Issuing New Music Record NFTs

The music publishing process on Sonorus is defined as issuing new copies of Music Record NFTs, which literally is an operation that mints new BEP-1155 NFTs on the blockchain that carries the same data as the original music. Each Sonorus user serves as a music collector with the ability to generate an unlimited quantity of new copies for Music Records in the Sonorus Catalog at the issuing prices generated by the following pricing model.

### Incremental Issuing Price Inflation Model

In order to achieve a natural balance between the copy amount of Record NFTs in circulation and the market value for Record NFTs, **Sonorus places no restrictions on the number of copies that Record NFTs for a piece of music can generate.** Instead, Sonorus implements an **Incremental Price Inflation Model** for the issuing price of new copies. In this model, for every new copy of Music Record NFT for a music piece issued by any Sonorus user, the price to issue another new copy will increase by a particular increment.

For example, a copy of a music record's initial issuing price is 20 $RUS, and the price increment is 1 $RUS. Then after 10 copies are issued, the cost to issue the 11th Record NFT will become 30 $RUS.

Currently, the default initial issuing price for all music in Sonorus Catalog is set to 20 $RUS, and the price increment for issuing an additional Record NFT is 0.2 $RUS per copy. If you are issuing the Nth record of a song, then the issuing price = 20 +0.2x (N-1).
