**Title: Clarification on Commercial Use of Fonts Embedded in LilyPond-Generated PDFs**
Hello everyone, A few hours ago, I posted a question mainly focusing on whether sheet music generated by LilyPond would be subject to any licensing restrictions that could affect its commercial use. I’ve since received some helpful responses clarifying that using LilyPond to create and sell PDF sheet music is permissible, and there are no commercial licensing restrictions related to the PDFs themselves. However, I now have a new concern, specifically regarding the default fonts embedded in the PDFs generated by LilyPond. Below is the information about the fonts used in my PDF file: ``` name type encoding emb sub uni object ID ------------------------------------ ----------------- ---------------- --- --- --- --------- NMTBXS+C059-Bold Type 1C WinAnsi yes yes no 7 0 YBXQWU+C059-Roman Type 1C WinAnsi yes yes no 9 0 PJJWOR+Emmentaler-14 Type 1C Custom yes yes no 20 0 PEHHCL+Emmentaler-20 Type 1C Custom yes yes no 18 0 GVAMCX+NimbusSans-Bold Type 1C WinAnsi yes yes no 16 0 ``` ### My Specific Questions: 1. **Are these fonts free for commercial use?** I plan to embed these fonts in a PDF sheet music file that I intend to sell on Amazon as an eBook. I want to confirm whether these fonts (specifically the C059 series, Emmentaler, and NimbusSans) have any commercial use restrictions. Should I consider replacing them with other fonts, or is it safe to use the default fonts? 2. **Assuming LilyPond does not affect the commercial licensing of the PDF** Based on previous discussions, it was clarified that LilyPond itself does not impact the commercial use or licensing of the generated PDFs. Therefore, my main concern now is focused on the fonts used within the PDF. 3. **Recommendations for Commercially Successful LilyPond and LaTeX eBooks** Additionally, if anyone can recommend commercially successful eBooks that were created using LilyPond and LaTeX, especially those sold on Amazon, I would greatly appreciate it! Thank you very much for your help and advice!
