Write the general structure and dynamics of the song on one instrument, such as a guitar or piano. Structure the song so that it includes an introduction, choruses, verses, a bridge and an ending, if you want to create a pop song. Structure the song in a less conventional way if you want to create a less-conventional song.
Record the piano chords or guitar part using an audio recording software program, such as Audacity or Pro Tools. Record the foundation of the song so that the basic structure and dynamics of the song can be developed by writing other instrument parts.
Write and record lyrics and a vocal melody that suit the mood of the guitar or piano part. Compose lyrics that repeat on the choruses and change with every verse, if you are writing a pop song. Alternatively, don't write lyrics at all, or follow a less-conventional format for writing lyrics.
Write a drum part by listening to the guitar or piano chords. Support and build upon the structure and dynamics of the song. Record the drum part.
Write piano chords or a guitar part, depending on which instrument you have not already recorded. Write piano chords or a guitar part that backs up, accents or harmonizes with the recorded instruments.
Write a synthesizer part. Choose a synthesizer and synthesizer tone that suits the mood of the song. Write a synthesizer part that plays throughout the entire piece, or only shows up during certain parts of the song.
Listen back to the recorded song and decide if you are happy with it. Change instrumental parts or even start again from scratch if you are not satisfied with the composition.
Download or purchase an audio recording program, such as Audacity or Pro Tools.
Create a new session in your recording program. Create a new track for each instrument or vocal part you will record.
Create a click-track to help you keep in time. Choose a tempo for the song and record each instrument while listening to the click-track.
Set up your microphone and headphones. Set the microphone signal level and the headphone listen-back level. Ensure the microphone signal is not so loud that it is peaking or distorting.
Record the fundamental instrument part, whether it is a guitar part or piano chords. Record-enable the first track and press "Record." Listen to the click-track on headphones while recording.
Record each instrument on a new track. Record-enable only the track you are recording to avoid recording the same part onto other tracks, and over other instrument takes.
Mix the song by adjusting the volume and pan of each track to create a balanced stereo mix. Adjust the equalization of each track and add compression, reverb and other effects.
Export the song as a WAV or MP3.
