I want to make a simple "done" tone using 555 timer or any simple IC

I want to make a simple "done" tone using 555 timer or any simple IC

As the title says, I want to make a circuit that makes a simple sound that indicates mission done or successful. The closest sound I found on YouTube is this one:

I found alot of interesting circuits using 555 timer but they only do annoying alarm sounds that can't work with my project. The sound has to be very kids friendly and as low frequency as possible. I also have to say the sound should be triggered via a pushbutton and I can't use any microcontrollers, only simple ICs.

حد مهتم يلعب شطرنج سريع (10 ثوانى لكل شخص)؟

كان بيبقى فيه tournaments على chess.com للوقت دا (10 ثوانى لكل شخص من غير زيادة بعد كل نقلة) بس معادتش بتتعمل ، فمعادش فيه طريقة انى العب ال format مع حد ، لو حد مهتم ممكن يتواصل معايا (الريتنج فحدود 1600) ، مش لازم 10 ثوانى بس ممكن لحد 30 ثانية ، بس بعد كدا بتبقى اللعبة مش ممتعة بالنسبالى بصراحة
