Guitar Challenge (Improv) - Acoustic Pop in G Major (Justin Sandercoe backing track)

Welcome to the Guitar Challenges. Each ‘challenge’ is basically an open invitation to anyone and everyone to play a song, an improvisation, a study-piece etc and post a recording – just for the fun of it.

So, whether you are a relative beginner learning the basic chords and strumming pattern of a song, a more experienced player adding a little fancy fretwork, if you want to do a little finger-picking, or you want to sing and play at the same time … you can join in with these challenges.


  • The challenge is to yourself.

  • These are not competition threads.

  • There are no prizes for making the ‘best’ recordings.

  • There is no shame for being at the beginner stages.

  • This is for FUN!


If you do want some constructive advice and feedback on your playing then that is cool. Just ask. Otherwise this is all about positivity, encouragement and having a go.

This challenge is all about playing some improvisation over Justin’s G Major Acoustic Pop backing track. It is track 1 on the Jam Major Vol.1 here: Jam Major Vol. I: Guitar – JustinGuitar Jams

The Backing Track is freely available here: Stream G Major Backing Track ( by justinguitar | Listen online for free on SoundCloud

To help navigate the song and develop your improvisation, this may help.
This chord progression and song structure is:
Section A: G / / / Gmaj7 / / / C / / / D / / /
Section B: Em / / / Bm / / / D / / / Am / / /
Section C: C / / / C/B / / / C6/A / / / C/G / / /[/pre]

Time Section
00:00 two-beat drum intro
00:02 A x2 intro (single strums)
00:25 A x4
01:06 B x4
01:51 A x4
02:33 B x4
03:17 C x4
03:58 B x4
04:43 B x1 outro

For soloing, you can simply concentrate on playing from the G major scale throughout. Note – watch for the occasional ‘sour’ note. For the more adventurous, these are some additional choices:
Section A - G Major (or G Maj Pentatonic)
Section B - E Aeolian (or E Min Pentatonic)
Section C - C Lydian (or C Maj Pentatonic) - emphasise notes C, D, E, G

It is approaching ten years ago that I immersed myself in the CAGED patterns of the G major scale and came up with this one-take improv:


Today I’ve been tinkering with the USB gain setting on my combo amp as advised in another thread, then I found this guitar challenge. Here’s what I came up with:

Listening to it now, I think I should have played more sparingly, but I had some fun ideas towards the end. I’ll definitely make more attempts at it.


I enjoyed that, Jozsef. Sounded good, the melodic ideas and your guitar tone.

Well done.

Thank you :slight_smile: At first I tried it with a bit of delay added to the tone but that clashed with the backing track, so I settled on this one.

Was really cool Jozsef as David said some nice melodic sequences, it was a very nice improv :slight_smile:

You are doing well Jozsef, some good tones and little runs going on here. Had to smile as soon as the first few bars of the BT opened, memories of early mashed up impros when I started the IM a good few years back. Thanks for sharing. :sunglasses:

Nicely played, Jozsef. It’s great fun to start playing along with backing tracks. I’m still at the ‘starting to’ stage, but I really enjoyed yours. It was melodically interesting, with some repetition as well. Great to hear you playing.
