Welcome to my interval trainer. Don't worry, there's not supposed to be sound. This tool is only meant to help you identify interval spellings. It has nothing to do with ear training.
Controls are on the right. You can use manual or automatic operation. In either case, a random interval is chosen, and two of the three boxes on the left will be filled. Your job is to identify the contents of the third box.
Under each box is a list of possible values. These determine how the random intervals are chosen. Any value not checked will not be displayed in its corresponding box. Make selections based on what you want to practice. See the presets menu for suggestions. You can get more accidentals, including double sharps (denoted by "x") and double flats, with the button under presets.
Capital letters in parentheses next to operation controls are keyboard shortcuts.
Enjoy. If you have any questions, comments, or suggestions, you can email me at firstname.lastname@example.org.
Selected values yield no possible intervals.
Check more boxes.
