So, you never answered whether there were any lights on (dash warning lights or interior lights) while this is happening. The only thing that comes to mind with the chimes going on at idle/low speed and off at higher speeds is that you have low oil pressure. If that's the case, the oil lamp should be lit.
This could be caused by a faulty oil pressure sender, which is $20 or so. Or, it could be that you actually have low oil pressure, in which case you likely have found out by now, because the engine is seized, and your mom has called you to rescue her from the roadside.
