## What is Trombone+?

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.

### 1/5 — I want a refund!

*2019-07-13, version 2.0.1*

There’s no sound!

### 3/5 — Really nice app IF THE SOUND WORKS

*2015-06-03, version 1.0*

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.

### 3/5 — Could be better

*2015-05-16*

When I first started the app I was impressed. I could tap on the ledger line, knowing it’s a bass clef and it tells me the note and plays what it should sound like, also showing me the slide position for the trombone.
The downside to this app is when I select the songs, the warm up scale, a great way to begin practice, all it does is highlight in blue which ledger line it is, no note value, no sound. A bit of a downer considering this has the potential to be a great app for beginning trombone players. I had to write down the ledger lines so I could tap them individually to get the note value, sound and slide position.
It’s like the app hasn’t been completed yet. I’m hoping this is the case and the songs will be completed with sound, note value and slide position. Please app developers….Please.

### 2/5 — High Notes!

*2014-12-30, version 1.0*

I bought this app to help me with high note positions and sound and it doesn't go above a high F.

### 4/5 — Trombone

*2013-09-16, version 1.0*

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¢.

### 5/5 — Trombone app

*2013-06-03, version 1.0*

Nice and simple. Just what I needed for review and practicing scales.

### 2/5 — Not enough

*2012-04-01, version 1.0*

App needs to be able to add more sharps and flats along with higher and lower notes! Also doesn't play the songs!

### 3/5 — Good

*2012-01-30, version 1.0*

Does what it says, but very easy to tap the wrong note

### 5/5 — Awesome!

*2012-01-27*

I was needing something to help me with my tone and this is the perfect app! I can hear the note and then play it myself! Awesome!!

### 4/5 — Trombone

*2012-01-20, version 1.0*

This app will help you with your skills.. You should buy it if u play the trombone=)
