Two-Second Sonic Logo Brief

Brief a two-second sonic logo. It must be recognizable after a few hearings and not a song. BRAND Name: [BRAND] Adjectives: [3] Where it plays: [APP OPEN | AD END | BOTH] What it must not resemble: [A FAMOUS STINGER I NAME, AN ALARM] Instruments or palette: [SOFT SYNTH | ACOUSTIC | A SINGLE TONE] Accessibility: it should not be painfully bright or rely on a frequency a phone speaker cannot make. BRIEF Duration 1.5 to 2.2 seconds. Describe the shape: attack, the note or noise, the ending (a clean stop or a short tail). The feeling in plain words. A version that is even shorter for a notification, derived from the same motif, not a different idea. Deliverable list for the designer: a dry version, a version with the tail, and a version that still reads on a phone speaker. No lyrics. No a full brand anthem — this is the mark, not the song.
