甚麼instrument最貴又最平?

我諗是小提琴了，最平的只賣百幾港元(二手)，新的也只不過三、四百港元，而最貴的珍藏品則可去到數百萬美元(即幾億港元)一把。我想樂器之中都算差額最大的了!

鋼琴最貴，最平一部直身琴都要過萬；陶笛最平，$22有交易。

口琴 guitar violin 最平. guitar cheap one less than 200, violin not more than 200 piano cheapest few thousand even used , as professional insturment i will pick violin or guitar to learn cheap cost than piano coz u need to buy the insturment is expensive, if piano go to store to practice not convince.

應該是豎琴(harp)最貴
最平應該是口風琴

結他羅我林
百幾蚊又有支
貴既話....我林都可以好貴掛

I think recorder is cheap, but not a good instrument

The most expensive instrument should be violin, which can cost more than a million US dollars.

However the cheapest can go down to $200 HK dollars
