A · Worked example
Major third
Sounding pitches: C#4 · F4
Listen for a broad size first: a step, a moderate skip, or a leap toward the octave. Then choose within that neighborhood.
C#4 to F4: 4 semitones, ascending. Major third.
Listen, compare, then practise
First decide whether the leap is small, medium, or large. Then compare the nearest interval names. Replays do not reduce your score.
B · Compare the difference
Perfect fourth
Sounding pitches: C#4 · F#4
Compare the labeled examples and identify the semitone distance that distinguishes them. The complete candidate list is shown below.
C#4 to F#4: 5 semitones, ascending. Perfect fourth.
For aural examples, sounding pitch names are a listening reference. Written-note exercises preserve the displayed spelling.
Check the idea: Choose the full interval name; direction alone does not identify it.
1 · Guided practice
Reduce each guided question to two plausible names, replay, and check the explanation for the specific distinction.
2 · Independent practice
Work across the full selected set. Keep a note of the two names you confuse instead of treating all errors alike.
3 · New-question check
Identify two new pairs after corrections. These use new generated input and remain separate from familiar-question retries.
Each session starts with two guided questions, then your chosen practice set, followed by two new questions at a different tempo. First answers, same-question retries, and the final check have separate results.
