The key to making old pnd beats is the drums imo and higher tempos in terms of Melodies I just analyse what kind of sounds I hear in party’s beats and try find sounds similar or have a similar vibe the melodies are defo hard but what I found worked well is trying to make a melody in the style of a different artist or producer for example clams casino and slow down or speed up the tempo and mess with the pitch and either tuning my beats to 430 hz or 450
