Creativity in "Sims 4" are quite profitable in the long run. If you play without codes for money, surely at least one of your sims is engaged in at least one type of creativity from those proposed in this part of the game.
As for music lessons, without a job, they will not initially bring a simoleon, unless you play for tips in various public areas. But keep in mind that playing for a tip is available only to guitarists, and only if you have at least a third level of guitar playing skill. There is also an opportunity for violinists and singers to make money: just start playing the violin or sing, and the sims passing by will begin to “tip” your musician. But pianists and organists in no way will be able to earn on tips, and for sim-musicians playing other instruments, this "earnings" is unlikely to be sufficient.
Thus, the most profitable way to earn money is to publish your own works, and for this you need to know how to compose a song in "Sims 4". This article will help you with this.
How to compose a song in "Sims 4" on a guitar and a violin
When pumping the skill of playing the guitar to level 8, you can compose songs using the action that pops up in the menu when you click on the guitar. The songwriting process takes 12 sim hours, but it is not necessary to compose a song at a time. If you are not finished, you can continue by clicking on the notes that appear in the luggage as soon as you start composing again. You can sell the rights to your songs from the 9th level of the guitar playing skill. In this case, license fees will be sent to you daily, but you can publish a new song only after one sim week.
In the exact same way, this also works for violinists.
How to compose a song in "Sims 4" on the piano and organ
To compose music on a piano, synthesizer or organ, you must have at least the 8th skill level of playing an instrument. With the 9th skill level of the game, you can publish your works and receive royalties for them according to the same rules as guitarists and violinists.
Options for songwriting in The Sims 4
Sim vocalists can compose songs from the 8th level of the singing skill, and publish them from the 9th, there is nothing special here. However, unlike other skills, the singing skill can be used to compose songs with instrumental accompaniment. Thus, if you have at least the 8th level of the singing skill and at least the 3rd level of the skill of playing any instrument (except the organ), you can compose songs for vocals and, for example, guitars.
As you can see, there’s absolutely nothing complicated about composing songs in The Sims 4.
