The notes are important, the means of playing them is not. Use a pick. 
In the Learn more section Justin writes to start using the open position scale. By this he means the scales you have learned in Grades 1-2 namely C major scale and E minor pentatonic scale. If you then learn pattern 1 of the G major scale (a closed pattern, not open) and more patterns beyond, you can use some or all of those.
Justin talks in the video about adding vibrato. I donāt remember covering this yet, unless Iāve somehow skipped over it?
Hi Matt, @aliomenti
https://www.justinguitar.com/guitar-lessons/vibrato-hand-style-te-103
I canāt find where it is taught for the first time in the course, but there is a lot of attention for it in the Technology section that you have to can do 
in between

Greetings,Rogier
There is a Grade 3 lesson that comes later than this one. Hereās how to find it (teach a man to fish, and all that):
You could also google āJustin guitar vibrato lessonā, which also works.
I have a quick question. When practicing for this module, are we supposed to just solo with the melodies or try to arrange a full chord melody? I find nailing the melodies not that hard, but trying to identify what chord goes over it and in which beat it goes super tricky.
Had a view of this lesson as well tonight and it appears to me that you have to know how to sing to get this. As I couldnāt hold a tune in a bucket Iām not seeing the benefit of the practice for this!
Also it appears that we need to know the notes on the neck to be able to do this. I can work them out but couldnāt point to a string/fret and know what note it is straight away. Are we supposed to know this at this point of the beginners course?
Lastly is it just the vocals of a song that is the melody?
Youāve missed the whole point of the lesson @Stuartw. You donāt need to sing or know the notes on the neck. But you do need to be able to hear a melody. Practice humming the melody then try and figure it out on the guitar using single notes. I know you have a hard time hearing but I think you would benefit from learning to hear melodies of songs.
You may well be right but he does talk about singing and notes on the neck!
I can do the first bit but trying to figure out what notes are being played/hummed Iām not so sure about. I know itās about finding the first note and that knowing the chords will help with this but not being able to sing (in tune) wont help.
Correct and not getting any better!
Stuart
To help with the note you hum compared to the note you pick, try reverse engineering.
Iām sure you will be familar Julie Anrews and do re me fa so la ti do. You should also have learnt the C Major.
Try playing the scale and humming each note or even go full Julie and sing the solfege scale note by note.
Pick C sing Do then hum tbe note.
Pick D sing Re then hum the note etc
Get used to how the hummed note sounds against the picked note. Practice until you can hum the scale, then try again finding melodies.
Hope that helps.
So is this the singing bit of a song or the lead notes?
Iāve tried this but itās really difficult with humming as I hear whatās in my head and not the noise coming out (if you understand what I mean) due to my plastic ears. Tried the singing option but thatās not much better as by ādoā sounds more like a croak!
A bit like transcribing I may just have to admit that Iām not going to get this, but thanks (both) for your help.
The melody is what makes the song. Have you ever noticed there are 1000ās of songs with the same chords but they all sound different?
What makes them different is the melody. This is what Justin wants you to learn to hear. Without the melody every song would sound the same.
The vocal melody.
Hi, I just tried this using Happy Birthday as the tune. Was slow but super rewarding to end up with a tabbed versionā¦I feel I have got the idea of what Justin is asking so ready to start on his suggested tunes now! Up to this point, they were a bit daunting. The basic start helped keep my enthusiasm for doing this - hope it helps a bitā¦
vibrato is string bending ?
In a way yes but they are different techniques.
You bend a string to play a note higher than the one you fret. That could be a half tone, whole tone, a tone and a half or even two tones.
With vibrato you are oscillating the string by usually smaller degrees to keep the note singing out. And there are many different ways to do that. The most common is a similar motion to a bend but you are pulling the string down and let it return to the original pitch and repeat that action for as long as you want the vibrato to ring out. The speed at which you do this can also vary.
The note does not have to be bent to play vibrato but you can add it at the top of a bend as well.
Hope that helps.
As i love the idea, I need to say that it is very difficult to me, especially as i though I have no musical hearing, at least I cannot sing.
So I opted for a simpler immediate step - playing some melodic exercises (such https://youtube.com/playlist?list=PLTSTNcRhbUph8-frFp0PKfO8tO8LDZNZG&si=t5wYI7IDIzMOfF5B but there is surely plethora of others) and always sing each melody and then play on the guitar.
It seems to works like a miracle for me - I realizes that I can repeat the melody on the guitar and I can sing it as well now. And as an side effect, I am learning the notes on the fretboard.
The plan is to improve the basic skills and then learn how to transcribe whole songs as shown by Justin.
Anybody doing something similar? What is your experience?
a bit similar to orf, iāve been following along with the practical theory course, which has some āplay what you hearā lessons that tie in with this, along with the ear training thing. i took one look at this lesson and thought:
This short is a very useful resource to help with playing a melody and a melodic solo, itās useful because it helps a great deal with dexterity and helps develop speed. Itās whatās helped me to be able to play some of the stuff that I have learned recently! https://youtu.be/6EyoRwDBSBk?si=Qm95zznzjZZFCmzt
Why does the melody not begin with the root note of the first chord (c)? Thanks.
