The pTrumpet is plastic trumpet.
I've seen a video of Alison Balsom play one. But she's a trumpet Goddess! She could rolled up piece of cardboard sound good.
For a kid in year 4 of trumpet, in school jazz band that recently rated 'silver' at a judged festival, picked for a solo (basically a bit above average for 8th grade) are these pTrumpets playable?
By comparison my Dad has played sax his whole life, but finds most 'travel' saxophones nearly unplayable.
I wonder if these pTrumpets are reasonably playable.
