Yes I know, another tuner app, but this one seemed like a good idea when I started so I persevered.
As a trombonist in a British Brass band (with occasional forays into Orchestra, Big Band and Concert Bands ) I have encountered many Brass Band euphonium players who can't or won't read bass clef so I've come up with an tuner app which displays the note you are playing on a stave rather than showing the name of the note A Db etc. The theory is you just play notes into the tuner, look at the display and teach yourself a new clef or transposition.
I know it doesn't take very long from my own experience 50 years ago.
Look at the display and subconsciously relate the position of the fingers, lip sensation, pressure, breath control and sound of the note to the note displayed on the stave.
This is aimed at beginners learners and amateurs not virtuosi who've been through college.

By brilliant design or probably good luck I ended up with a mechanism whereby I could implement lots of transpositions quite easily so I've got all the Trombone clefs plus Trumpets in A, Bb, C, D,Eb and piccolo, a few Horn transpositions, Woodwind, Sax family, Strings and Voice. I've checked them all myself but I'm not the worlds greatest completer finisher and I can't get beta testers for everything so I've let it loose on the app store.

And with great trepidation I post this video

Sorry but the cornet lives in the cupboard. And you'll be relieved to know it's gone back in there.


It only takes up 500kb on an iPhone and its free so I wondered if it was any use to anyone who teaches.
Might be helpful to learners who have difficulty pitching notes as well as people who want to learn transposition or even singers who don't have perfect pitch.

I've used autocorrelation for pitch detection so it may not be as accurate as some of the more professional looking tuners on the app store especially below F2 but seems OK.
Tuner bar goes green when within 2.5 cents of true so this may be a bit tight especially as intonation is different for anything but root and fifth depending on the key.
