Let's create a new software instrument. And for this we're gonna try and find a bass instrument, so a low pitched instrument. The ones that will work best for this will be bass guitars or double bass, or it might say upright bass. I would steer clear of synth basses because they won't really blend well with the acoustic instruments that we've chosen so far. So stay away from synthesized ones. But other than that, you choose one that works for you. I'm gonna go for this upright bass. (upbeat music) Which is a double bass. I think that works quite nicely with the instruments I have so far. So the root note of a chord is the bottom note of a triad chord, and it's also the letter that a chord is named after. So a G major chord, for example, the root note of that is G, a C minor chord, the root note is C, it's the same with extended chord. So if we have a G major seven chord, the root note is still G. If we have a C minor six chords, the root note is still C. So it's that first letter. So we've already recorded in the chords, you can see mine here in this piano track, which means that we should be fairly familiar with the chord sequence, but I'll just talk through it. So bar one, we're starting on G major seven, so I'm gonna play a G. (gentle music) Same on bar two, bar three I go to A, and I stay there for bar four and bar five and bar six, and then back to G, bar seven, then up to C, then back to G, then up to C. And then we finish on G for the last four bars. So fairly straightforward. If you look at my keyboard here on the screen, we use G, we use A, and we use C. They're the three root notes that we need to find. So before you record, have a go at just running through those root notes so you're happy with the sequence of them and you found them on your instrument.
