You don't know what you are missing until you try it right? Samples can be whatever you want, whether it's chords or just you talking. Get creative buddy!! And share your creations with us please 🕊️
That's always the gamble! Why not just make the tune for your own pleasure, and if people enjoy it try looking down that route, produce and share it first 👐😎 My understanding is if you can show it it sounds like you have registered the sample even if it's copyright one, then you are ok? Please don't quote me in your lawsuit though, unless you wanna educate me after 😂🙌🤗☮️☮️🕊️🎵🎶😁 The "original source" are extremely unlikely to sue you if your song is unknown. The sung will be unknown without publishing it. The sung might not match theirs. If say it's worth a shot and releasing your own and enjoying the music. If you are a performance artist you can make music. If you produce then if day it's more for sharing...
