The following are the steps to create a mini-world song:

Choose the right software: First, you need to choose a professional music production software, such as LogicPro, AbletonLive, FLStudio, etc.

Determine the genre and theme: Before starting production, you need to determine the genre and theme of the song, and prepare relevant lyrics and melody.

Create melody: Use MIDI keyboard or mouse to create melody in the software. You can use the software's built-in music materials or record your own instrumental tracks to add to the song.

Arrangement, tuning and mixing: Use the audio effects, synthesizers and other tools in the software to process and change the sound, and adjust the volume and harmonics of various instruments to make them richer. Properly tune each track's tone and then mix it.

Add lyrics: Write the lyrics, arrange them according to the beat of the song melody, and add background chorus or other vocals as appropriate.

Record vocals: Prepare a professional microphone and record vocals in a recording studio or a quiet place. During the recording process, pay attention to maintaining adequate volume and sound quality, and perform appropriate post-processing.

Final production: After processing the vocals and mixing them with electronic tones, you will have a complete musical product. Carry out the final post-production and export the music after completion. You can choose mp3 or WAV format for storage.
