Compose a dynamic and cool rap beat with a two-minute duration, set at 90-100 BPM, adopting a modern Lo-fi style. Ensure the drum pattern is punchy and tight, featuring a prominent kick, snare, and hi-hat, complemented by intricate percussion elements. The bassline should be deep and groovy, incorporating slides and glides for extra style. Create a catchy and variable melody using synthetic, piano, or guitar sounds. Add harmonies or chords that amplify the melody, and play with chord progressions. Apply effects like reverb, delay, and EQ, and use automation for dynamic shifts. Integrate smooth transitions with elements such as risers, and structure the arrangement like a typical rap song. Include modern and fresh instrumentation with unique sounds or samples. The energy should escalate steadily, maintaining a balance of intensity and subtlety. The beat should be compatible with empowering, confident, or narrative-driven lyrics.
