Blowing a flashlight is more breathless than playing a saxophone?

A flashlight is better. As long as the finger is pressed in the right position, the sound (note) can't be wrong, and the tone can be easily changed. But saxophone needs the player to exhale continuously to make saxophone pronounce continuously, so flashlight is better.

The advantage of electric blowpipe is that it is convenient to change tones and has various timbres, which is equivalent to having a variety of musical instruments, which is super fun. External speakers do not need to consider the problem of microphone reception.
