File Extension GP3

Files with the file extension GP3 are associated with Guitar Pro 3, which is a musical notation software program for guitarists. Guitar Pro 3 allows you to create and edit musical composition scores for guitar, learn how to improve your technique, and use musical tools, such as tablatures for the fretboard, a tuner for tuning the strings, and a metronome for counting note values as you play.

GP3 files which are created by Guitar Pro 3 contain tablatures for the guitar, which is a method used for reading chords and guitar notes using a six-lined staff. Instead of the staff resembling a conventional five line musical staff, the guitar tablature staff represents the six different strings on a classical guitar, electric bass, or banjo.

Guitar scores that are created using Guitar Pro 3 can be played back using a Musical Instrument Digital Interface or MIDI file, which is a standard that is used to connect musical instruments with computer technology. GP3 files are a part of MIDI technology and allow guitar players to create and edit digital music tracks using the tablatures contained in this file type.

How to Open GP3 Files

The best way to try and open GP3 files is to double click on the file to see if it will automatically open in a default application. If the GP3 file was created on your PC, chances are you have the appropriate program installed for opening this file type.

If the above method is unsuccessful, it is necessary to download and install Guitar Pro 3 in order to open and read the file. You can obtain a free download of Arobas Guitar Pro 3 from the Softonic website. Guitar Pro 3 will act as a guitar effects processor and open GP3 files so you can view and edit the contents. Guitar Pro 3 is compatible with all versions of the Windows operating system.

If the GP3 file is associated with Musical Instrument Digital Interface files, MIDI files are text file types. If you want to view the contents of the MIDI file to use it with the GP3 file, you can open this file type using any text editing program, such as Notepad or WordPad for Windows, Apple TextEdit for Mac, or gEdit and Nano Editor for Linux.

If you use an operating system other than Windows, you should check the SourceForge website at to see if there is an open source program for reading guitar tablature files. Although GP3 files are created with a Windows-based program, you may be able to open them using an open source program that is compatible with your operating system.
