Global Metadata
Genre: cyberpunk UI alert / neon synth ringtone extended into a short stinger. BPM: 140. Key: F# minor. Cold, digital, futuristic.
Application: take a half-second neon firmware chirp and develop it into a 10-second cyberpunk ringtone / HUD alert motif. Same sound world throughout.

Vocal Details
STRICTLY NO HUMAN VOICE. No singing, no hummed notes, no vocoder voice, no choir, no breath, no mouth sounds, no syllable-like tones. Zero vocal content.

Arrangement
Pure synthesized cyberpunk electronics only. Open with a sharp neon square/saw blip / glassy digital ping / FM bell glitch, then extend and evolve that same machine motif for ten seconds: repeating UI chirps, short arpeggiated neon pulses, digital glitch ticks, cold synth stabs. No drums bed, no bass groove, no pads wash, no orchestra. Dry, punchy, hardware-firmware character — develop the ringtone, do not turn it into a song with a singer.
