Trombone+ is an interactive fingering chart for tenor trombone. Tap the music staff to see the note, its name, and slide position, PLUS hear its sound.

Use it to look up a note. Or, tap out a melody on the staff just for fun.

Learning to play the trombone? Play along with the following animated songs:

Warm Up Scale
Hot Cross Buns
Mary's Little Lamb
Twinkle Little Star
Frère Jacques
Jingle Bells
Concert B-flat Scale and Arpeggio
Lightly Row
Can Can
Ode To Joy

In settings, change the tempo of the animated songs. Just learning? Go nice and slow. Once you get the hang of it, increase the tempo, and for an extra challenge hide the note names and fingerings.

Notes are for a tenor trombone in bass clef and range from E below the staff to high F above the staff. All flats and sharps are included.

Really nice app IF THE SOUND WORKS

It's great that this app has a lot of features for just 99 cents, but the problem I have with it is that there is no sound when I tap on a note on my iPad 2. Only if this is fixed would I give a five star rating.

This has been very helpful for my beginning 5th grader. Two suggestions, however: It is very easy to hit the wrong note as the spacing of the staff lines are quite close together. It would seem a simple fix to make it easier for those of us with fat fingers (although before using this app, I never considered my fingers to be particularly fat!).

Second: it would be nice if the note would play for a longer period of time-- perhaps so that a student could match their note with the actual note coming from the app.

Other than that, a good program for 99¢.
