In March 2018 I gave a short list of six sites that I have used to access music for the classical guitar. Here are a further two sites plus an additional Delcamp page.
393 free to download, modify, print, copy, distribute, perform, and record – all in the Public Domain or under Creative Commons licenses, in PDF, MIDI, and editable LilyPond file formats.
Another page in the delcamp offering of free CG music in .pdf format. It also has an extensive list of works arranged in alphabetical order by composer.
596 pieces of music, collections, primers, and books. By clicking on one of the five column headings you can sort by either Title, Composer, Form, Period, or Rating.
For those who missed the first list and want everything in one place, here I the sites previously provided:
This site lists over 4,600 pieces in .pdf format. There is no real difficulty grading system but it does list 1,173 pieces as ‘easy’. Some of the pieces have a difficulty indicator when you click on the actual selection; for instance, Tarrega’s Lagrima is marked ‘Grade 4 Late Intermediate’.
Bradford Werner has provided a nice, but by no means comprehensive, selection of graded pieces. The added value of this site is that he provides video lessons for most of the pieces listed.
The Petrucci Music Library contains a huge database of public domain music for all instruments. It is not easy to browse this collection, but the search facilities are adequate if you are looking for a composer or a particular piece. For instance, a search for ‘Tarrega’ yields 51 pieces and a search for ‘Largrima’ yields no less than 7 available transcriptions. Unfortunately, there are no indications of playing difficulty. However, you could use www.guitarburst.com in conjunction with this site for most free guitar scores.
This site has over 600 scores, with basic difficulty level indicators, and an online synthesised audio/visual playback facility. However, it only allows a few views/downloads per every 24 hours unless you take out a paid subscription to the site
A reasonably good range of free music scores as well as methods and collections, but this is the site of the Guitar School of Iceland and so the commercial sections contain a lot more material for which you will have to pay if you want to download them.
This site is more than just a forum and contains sections of graded classical guitar music. The drawback is that you have to become an active member of the forum in order to access most of these collections. In addition, the choice of music tends more towards the Baroque than anything else.
