ChordPulse can let you quickly choose and modify chord progressions (with backing instruments) that you can loop in lots of ways. That way you don't have to record anything.
It comes with lots of musical styles too. The 30-day trial is free and after that you can buy it or use a lite version of it. I can't hear a looping chord progression without getting ideas so I try not to do it too much.
Part of the magic is that as the progression is playing, you can instantly drag your mouse to alter it. For instance, you might stretch out one chord, inject a new one and alter an existing one as the music plays. You can even build an entire song because it lets you place different progressions on different "pages" where each page might represent a song section.
I never tried reading poetry at the same time, but that sounds like a good idea. I'll give it a try.
One of Sia's creation methods is listening to a track and coming up with melodies and sometimes lyrics. On a YouTube video you can hear her stumble upon the words "shine bright like a diamond" as she was singing sounds to a track. That song became Rhiana's "Diamonds" song.
I often hear music and words whenever I hear something playing. Others do too. For me, what's playing may be something as simple as a metronome, a simple rhythm track or music I barely hear in the distance. That also happens when I hear chord progressions.
But that's only one method in the creation process. Maybe you are naturally suited to hearing beats or music and coming up with melodies and words. You might want to capture those you think are good.
Those snippets of lyrics and melodies aren't songs however. You'll have to create an actual song and some of the things you come up with may in some way be used in songs. Since rhymes are important in hip hop, you'll need to factor those in too.
You might try the free trial of ChordPulse. It can play chord progressions you create or those that come with it. You can lower the volume on tracks you don't want to hear. Tracks are percussion, chords and bass. That flexibility will let you only hear percussion if that's all you want to hear.
Band in a Box is excellent for this. Very versatile, although pricey for the full version.
[edit] this one also looks promising but minimal (no drums?). Free 2 week trial: ChordPulse
Check out ChordPulse.
Not quite the same, but still a nice tool for finding chords and experimenting with melodies. As it has midi-file support, I'm using it now and then in connection with a DAW and some VSTis.
If you need some backing tracks you could use Chordpulse. You can use it's built-in chord progressions or make your own. It also comes with lots of built-in song styles you can tweak. You could sing along to the backing tracks and play a guitar if you like. A multitrack recorder can make that possible. If you feel comfortable using Audacity these days, you could use that to record it all.
Good luck with the proposal. It sounds like fun. And since you want to make a fun song, maybe there won't be much pressure you might feel to make a serious one. Once you get a song, you're not far from putting it into a music video. There are easy ways to do that too.
Loop them any way you like at the measure level or at the song level. The trial is free and the Lite version is always free.
Here are the chord types that even include half-diminished sevenths. Export what you create to MIDI as needed.
Thanks for pointing that out. I assumed that you took this 6-week "Writing the Lyrics" course taught by Pat that you can audit for free. Reddit mention here.
If there's a "Writing the Music" course I'll look for that and the discussions about chords. John Mayer physically attended Berklee and said he learned a lot. Attending in person is probably different from auditing courses over the Internet.
You might try the Chordpulse desktop program which lets you play with chords in real time as the music loops. You can even write a song on it because you can create separate pages that represent song sections - then export the MIDI to a DAW. It comes loaded with chord progressions and musical styles played by percussion, bass and keyboard/guitar.
It's possible to write melody and words without using chords because you or someone can add chords later.
Chordpulse comes with lots of built-in chord progressions and patterns you can listen to and study. Ideally you could sing something as chords play. And it may be possible to sing or even hum something without hearing anything.
But even if that doesn't happen, you can examine Chordpulse's chords and arrange them if you like to make song sections. The chords in the built-in progressions work well together and you've probably heard some of them in songs. You could probably learn to play those chords on your real computer since you can visualize a chord's notes in Chordpulse.
That's a trial. When the trial ends you can buy it or downgrade to a free lite version.
After you play a chord or before you play a chord you can say a word. Listen to songs and you'll see that in action. When you say something helps shape a melody.
This is a short video recording of Sia singing on top of a pre-existing track. She sings a mixture of nonsense words and real words. Sometimes good words come out which she keeps, like in this session where she came up with some of the lyrics for Diamonds. Her goal was to come up with melody.
She writes very fast but this isn't the only method she uses. She uses what she comes up with to complete the song.
I think a term might be "gibberish singing" which many writers appear to do. In that Sia recording, she's coming up with syllables which in turn may spark some words. But apparently her main goal was to come up with a melody for the existing track she heard.
You can do the same thing if you like. There are lots of tracks you can sing over. You can even sing over basic rhythm tracks produced by a program like ChordPulse (free trial). One suggestion might be to dump what you come up with into a DAW and sing additional tracks on top of what you already came up with. You'll wind up with several vocal tracks and when you hear them together, you may identify good words, phrases and ideas from the mix.
I also sing over existing tracks but that's only one small task in the writing process. In addition to music, you have rhyme, song structure and what you actually want to say to deal with.
when you can't sing you can draw some melody notes and then select all and import your lyrics with https://synthesizerv.com/en/ and i managed to get the free standalone editor,so look for it , and you can import a band-in-a-box audio file or maybe the free http://www.chordpulse.com/lite.html and record the audio.
