Is the written part of your Music portfolio earning its marks?
Paste the written work from your exploring music in context portfolio and get feedback on criteria A, B1 and B2 in about a minute, with the words counted against the 2,400-word limit.
Ask your teacher first: the IB academic integrity policy asks students to abstain from receiving non-permitted assistance in the completion or editing of work, such as from friends, relatives, other students, private tutors, essay writing or copy-editing services, pre-written essay banks or file sharing websites, so check that your teacher and your school allow outside feedback on this work.

What the exploring music in context criteria reward (24 marks)
Exploring music in context is externally assessed coursework, worth 30% of the final grade at SL and 20% at HL. The portfolio holds your written work, up to 2,400 words, one creating exercise (a score of up to 32 bars and/or up to a minute of audio, as suits the style) and one performed adaptation of music from a local or global context for your own instrument, up to two minutes.
All the practical evidence goes into a single audio file of up to four minutes. Track lists in an appendix, citations and the bibliography are not counted in the 2,400 words.
- Criterion A: Selection of evidence, 6 marks. The diversity, breadth and balance of the music you chose as evidence: contrasting material from personal, local and global contexts, across at least two areas of inquiry.
- Criterion B1: Conducting musical research, 9 marks. How well you extract, communicate and locate musical and extra-musical findings, and how effective those findings are, using accurate terminology.
- Criterion B2: Implications, 3 marks. How clearly you explain what your research means for creating and performing in the styles you studied.
- Criterion C1: Understanding creating conventions, 3 marks. Your understanding of creating conventions, shown in the creating exercise.
- Criterion C2: Understanding performing practices, 3 marks. Your understanding of performing practices, shown in the performed adaptation.
C1 and C2 are judged on the exercises themselves, the score and the audio, which IBLens cannot hear or see. The report marks A, B1 and B2 from your written work, leaves C1 and C2 out of its estimate, and does not count the missing exercises as a weakness.
Mistakes the exploring music in context criteria penalise
- Evidence from one corner. Pieces that all come from the same context or the same area of inquiry. Criterion A rewards contrasting material from personal, local and global contexts across at least two areas of inquiry.
- Findings with no location. Saying what a piece feels like without pointing to where a feature happens. Criterion B1 rewards findings that are extracted, communicated and located, so give the bar or the timing.
- Loose terminology. Everyday words where the subject has a precise term. Criterion B1 asks for accurate terminology.
- Research that leads nowhere. Analysis that never says what it means for your own creating and performing. Criterion B2 asks you to explain those implications.
- Words past 2,400. The written work has a maximum of 2,400 words. Track lists in an appendix, citations and the bibliography are not counted.
Frequently asked questions
- Can IBLens hear my creating exercise or adaptation?
- No. It reads the text you paste. It marks A, B1 and B2 from your written work and leaves C1 and C2 unmarked, so the estimate is out of 18 rather than 24.
- What should I paste?
- The written work of the portfolio. You can add the track list: the official count leaves it out, and it shows the range of your evidence for Criterion A. The word count in the report counts everything you paste, so allow for the list when you read it.
- Does it mark the Music internal assessment?
- No. IBLens marks exploring music in context only, not experimenting with music or the other Music tasks.
- How accurate is the estimated mark?
- It is an estimate, not a mark. A language model applies the published criteria to what you paste, and it can be wrong. Exploring music in context is marked by an IB examiner, so use the report to find what to fix before you submit.
- Is it free?
- The first preview is free and needs no account: a range of totals that contains the estimate and, for most drafts, your weakest criterion with its feedback and the top risks in the draft. The full report, with every criterion it can mark scored and a ranked list of fixes, is $9.99, or $24.99 for five and $44.99 for ten.
- Is my work stored?
- IBLens never saves the text you paste. Our server sends it to Anthropic, the AI provider, to produce the report, and Anthropic deletes it within 30 days unless it is flagged under its usage policy or the law requires otherwise. Reports made without an account are deleted after 90 days unless you buy the full report, and reports in a signed-in account stay until you delete them.
What the Exploring music in context portfolio report covers
- A mark for criteria A, B1 and B2, with the reason for each one. C1 and C2 judge your creating exercise and performed adaptation themselves, which a pasted text does not carry, so they are left unmarked
- The risks costing you the most marks, ranked, with what in the text causes them
- Next steps ranked by the marks they are likely to recover
- Your words counted against the 2,400-word limit, with what the official count leaves out
- Two free re-checks of a revised version of the same work, within 14 days of the full report opening
IBLens at a glance
- Marks against the published IB criteria for each task. Where the syllabus changes in May 2027 (the Extended Essay, the Psychology IA and the Computer Science IA), it holds both sets and uses the one for your session. The Visual Arts comparative study is not set from May 2027, so it is marked only for 2026 sessions.
- $9.99 for a full report, which includes two re-checks of the same work within 14 days. No subscription.
- The first preview is free and needs no account: a range of totals that contains the estimate and, for most drafts, your weakest criterion with its feedback and the top risks in the draft.
- Covers coursework in 14 subjects, the Extended Essay, the TOK essay and the TOK exhibition.
- Our server sends the text you paste to Anthropic to produce the report. IBLens never stores the text itself; the report is kept as the Privacy Policy describes.
