Euphonium uses tuba sound by default, no playback above C5

S3 - Major

As noted by some forum posts (and mentioned in a comment on the Our Progress on MuseScore 4 but which does not show up under "What Links Here") the Euphonium, which should be very close to Trombone in terms of range, does not play above C5 (see attachment for playback of Trombone, Euphonium, Tuba and Baritone horn), even though these notes should be in (albeit uncomfortable / pro) range.

Reason for this: Euphonium does not have its own Sound, but uses the “Tuba expr.” sound (as can be seen in the Mixer. This sound does not have notes above C5.

Possible workarounds:

  • Trombone: has its own native sound
  • Baritone: uses the “French Horns Expr.” sound

I don't know what is the correct severity; it can be very jarring to have these notes just missing. I have seen Jojo's comment at, "None of these a part of GM, so would need some specilized and additional soundfont."

So should Euphonium use the Trombone sound instead? Or the French Horn sound?

That'd be a rather easy change.
Or is Trombone just similar in range, and the current Tuba sound is OK, just not going high enough?

In reply to by Jojo-Schmitz

If it were me, I would change it to trombone. Either option has its issues. To answer your other questions,

a) Or is Trombone just similar in range: Yes
b) and the current Tuba sound is OK: Probably yes. It is better than trombone.
c) tuba just not going high enough?: Yes

I asked the question on the forum, Euphonium sound does not exist, keep on tuba or change to trombone? and will point user on Discord to it.

If this is something that was done in the past with other instruments / instrument families with a reasonable amount of success/acceptance, it would be more preferred than the other two suggested workarounds.

Title Euphonium uses tuba sound by default, no playback of C#5 and above Euphonium uses tuba sound by default, no playback above C5

Amateur and professional ranges for reference:
aPitchRange: 40-70 Bb4
pPitchRange: 40-74 D4
aPitchRange: 40-71 B4
pPitchRange: 36-74 D4

We have 3 options:

1) looking at an online reference
Bb4 normal
F5 extended/pro

= add 5 semi-tones (C# - F5)

2) Same playback range trombone

The Trombone sound plays up to C7, which even though that seems totally outside of actual playable range, if we are going to treat euphonium sound analogous to trombone sound, I would say add/create C#5 - C7

= add 24 semitones

3) The alternative would just be to pick a number of semitones inbetween. 5 and 25.

My vote is for (2)

a) Are there instructions (howto / tutorial) for extending the sound range. I assume this would be called resynthesizing? If not, and someone can provide some guidance, I could document it properly for the next instrument in a similar situation.
b) I assume one would extend the tuba soundfont upper sounding range, and not create a clone and call it euphonium (since it is still a resynthesized tuba, and not a sampled euphonium). This will also make it clear what people are listening at, make it easier to choose a 3rdparty euphonium sound from the mixer, if they are not happy with the native (to MuseScore) sound and are ok to go through the effort of installing a 3rd part euphonium soundfont.

I have extended the upper range of the tuba for MuseScore_General 0.2.1 (and also the HQ version). In doing so, I have also generated new samples for the upper range for a better sound when used as the euphonium preset.

Until MuseScore_General version 0.2.1 is included with MuseScore, you can download the SoundFont here:

If you have trouble uncompressing the files, you can use 7-zip for Windows or The Unarchiver for Mac. Linux users should be able to use their built-in archive manager.
