Most of the time, a piano as light as this would just be put onto an X-stand. I only use X-stands for the lightest of keyboards - and never for gigging! A Z-stand will do fine instead, or one with four legs is even better. But for home use an X-stand will be plenty good enough. The screw holes are probably for fixing it to the $100 wooden stand made by Yamaha for it. (A quick Google provided this).
Even on gigs, keyboards are not usually attached to their stands. If you're in a situation where it's likely to get knocked off, then even attached, it's not a good situation to have it in! Velcro between keyboard and stand might be an answer.
Answer from Tim on Stack ExchangeSo I'm looking to get a cheap but durable keyboard stand for my Yamaha P45. I'm looking for something that won't cost a lot and won't wobble too much - if not at all - while playing. Is there a cheaper alternative to Yamaha's L85 Keyboard Stand (which is meant for the keyboard), or should I just cave in and spend the $100 on it?
