For the sake of this blog, the comparison criteria is, Tone, Articulation and Build.

Tone

It's a scientific fact that metal and plastic resonate differently. This is most obvious on the Trumpet when looking at either extremes of volume, (ff - pp.) In this instance, the Sonata wins. Furthermore, it also offers superior depth and clarity of sound. Even so, that is not to say that the pTrumpet is a poorer option. As has been said in other blogs, between these two models, the overall tone is more affected be the ability of the player than the instruments themselves. If you're good enough you can make anything sound good and, lets face it, as a total beginner you've got the ability to make a Strad sound like a giant raspberry.

Articulation

The pTrumpet valves are not always as responsive as its Sonata counterpart. This means the articulation is not as crisp. Yet again, for a total beginner or skilled player, this isn't too much of an issue. Also, while it appears that the Sonata wins this round it is worth being aware that the 'better' valves of a traditional Trumpet come with the cost of increased maintenance. For some this puts it firmly in second place.

*****

Build

While a traditional brass cornet - probably - has a higher tensile strength than the pTrumpet, it's worth nothing as metal dents and this plastic invention bounces. See 👇 The pTrumpet weighs only 500g. This is close to half the weight of most other models. This makes it ultra portable. On top of this, the extra light weight build makes this instrument perfect for young, developing players, as well as those who suffer with joint condition that would otherwise make it difficult to play.
