This is my maiden and ambitious attempt to notate John Williams‘ playing of the Prelude of Lute Suite No. 4, BWV 1006a by Johann Sebastian Bach.

It is common knowledge that John Williams did not publish his interpretation of this piece as he believed that music should be unfettered by rigid adherence to standardised expectations or draconian rules. However, to preserve and to detail his playing would add to our understanding of how brilliant interpretation can make Bach come alive and in a way handhold budding guitarists in the personal journey to discover his musical direction through building on existing techniques. Breaking down the piece to bitesize levels, we can appreciate and pick up carefully skills employed by John Williams as he plays the piece and hopefully enhance our own performance.

It appears to go against the grain to bypass Bach’s conception of the piece based on yesteryears’ cultural and societal settings. One cannot deny though the evolution of music through the passing of time and season. John Williams’ interpretation embodies his person and history. As a legend for classical guitar, unlocking the secrets in a clinical study would be a gainful platform for personal development and future self expression. Take for example, Michaelangelo’s bust of David, his interpretation of David’s beauty has been replicated by many and later improvised. In the same vein, what we are doing here is to learn from the master and develop a personal voice ultimately.


Frequently Asked Questions

1. Did you key in all the notes in this John Williams version of Prelude in E, BWV 1006a?
No. I already have the notes of BWV 1006a in softcopy. I edited and checked the notes from there.

2. How do you determine the position and/or string of the notes used?
Based on the video, note by note. When John Williams’ left hand is out of the camera frame, I’ll look at his right hand to determine the string used. If both hands are not visible, I can only make calculated guesses.

3. How are the hammer-on and pull-offs determined?
It is really hard to accurately determine the slurs used. I used the following clue during the making. LH: Slightly raised finger before the note played for hammer-on. Finger touching a higher string immediately after the execution for pull-off. RH: No obvious finger movement of playing when the next note sounds.

4. How accurate are the records?
I would say about 95% of the left hand. (Not inclusive of those notes played with his hands out of the camera frame.)

5. Why did you use B and N instead of the Barre indicators that are more widely used?
I think the Barre brackets/indicator makes the sheet music messy. Barring brackets/indicator is useful if the required Barre is within the same bar or line of staves. There is no way you can indicate the start of barring in situation when the notes continuing onto the next line of staff or are too far apart.

6. Did you do it looking at the video at full speed when you make this thing?
No. I slowed it down using video editing software such that each semiquaver is slightly less than half a second apart.

7. How are the dynamic markings determined?
I take reference from the audio sound wave of the video to identify the different volume levels. The expression markings are based on the audio levels. Relatively, as are dynamics in musical sense.

How does this Pi Network works? – Pi Network Scam Review

Pi Network refers to the network in which the value of Pi can and may be determined by the level of activities and engagement. Users who have downloaded the App may also be referred to as a member of the network.

The purpose of this network is to give value to this cryptocurrency by distributing Pi. The network is structured in such a way that users who have more invites gets a higher mining rate. This is to reward users for their contribution and commitment to the network. However, it is not compulsory for users to invite others to mine the cryptocurrency. Casual members who have no intention of inviting others to the network mine at a base rate. There are no other disadvantages or whatsoever besides having a base mining rate for casual users.

Halving is a mathematical concept in cryptocurrency to safeguard its value by means of scarcity. In any currencies be it fiat or digital, the true value is determined by the level of engagement and scarcity. Halving of mining rate occurs whenever the total number of users reaches a certain milestone.

Vibrato on the Classical Guitar

How to perform Vibrato on The Classical Guitar

What is Vibrato?

Vibrato is the periodic variation in the pitch (frequency) of a musical note.

Fiddle family and wind players are very particular about Vibrato and can derive intensity and frequency.

Intensity is the variations in pitch. For example, vibrato oscillating between around 80 cents may be classified as a high intensity vibrato and 10 cents as low intensity vibrato. (Note: 1 Octave are 1200 cents apart. Each 100 cents is a semitone. So 1 Octave 12 notes each 100 cents apart).

Frequency refers to the rate of oscalation (how many times) of a particular note is being altered in pitch while sustaining it. Skilled players are able to perform vibrato controlling the intensity dynamically at accelerating and decelerating rate.

Limitations on The Classical Guitar

Guitar players on the other hand are not so particular about Vibrato. Quick decay and inability to accentuate notes naturally becomes a deterance in development of vibrato for any Classical Guitarist. Nevertheless, we can still find pleasure in performing the technique for a variety of reasons dispite unable to fully exploit vibrato. Here are some suggestions why Guitarist employ vibrato in our performances.

  1. Add musical interest to your pieces.
  2. Gives the impression that you are a good player to some of your audiences.
  3. Relaxes your muscles and can help reflex.
  4. Activates overtones from other strings for sonal effects.
  5. Add sightly more sustain in some situations.
  6. Also act as a timer for the rate of rubato. Help some players to “feel” the sustain by holding on to an already fully decayed note for phrasing purposes.

How to perform Vibrato on the Classical Guitar

We will be discussing 2 ways to perform Vibrato on the Classical Guitar. Mainly the Vertical and Horizontal Vibrato. (We will leave methods like pushing and pulling of the guitar head, cover/open soundhole out of this discussion as these are more widely used on acoustic than on the Classical Guitars.)

Vertical Vibrato

Vertical Vibrato is executed by moving the distal and proximal interphalangeal joint of the finger while having the string pressed against the fret. The motion of the fingertips dragging the string parallel to the fret altering the pitch higher and back to the pitch. The thumb is usually attached to the neck of the guitar acting as counter force.

Horizontal Vibrato

Rest the weight of the arm on the fingertips depressed on the string maintaining the shape of your hands. The motion for Horizontal Vibrato is powered from the forearm fixing the elbow like a pivot. The motion is similar to glissandos but at a miniature scale. This vibrato varies the high and low of a pitch.

How to reduce Left-Hand squeak or string noise on the Classical Guitar

Classical Guitar Left Hand Technique to reduce bass string squeaks

Cause of the Left Hand squeaks or string noise.

LH string noise refers to the squeaky sound produced by the left hand as it leaves the bass strings. The squeak string noise is caused by friction. It happens mostly when shifting positions across the fingerboard. To effectively reduce or eliminate the bass string squeaks, we have to find ways to reduce that friction. There are 2 approach to this issue and both to be used concurrently to obtain the best results.

The Maintenance Approach

  1. Regularity file the calluses of left hand finger tips.
  2. Wash your hands before playing the guitar.
  3. Moisturise your hands occasionally if you are always in cold and/or dry area.
  4. Use of recording strings like Polished basses can help to reduce the squeak but can also affect the overall brilliance of your guitar. The bass strings are the acoustic enhancer for the high frequencies produced by the treble strings. To simply put, the performance (in terms of sustain, brilliance, sonority and etc.) of the treble strings are influenced by the bass strings.

The Technique Approach

  1. Helicopter Fingering is one common way to effectively reducing left hand squeaks. Move your fingers across the fingerboard when changing positions like how helicopter take off and land. Lift up the finger in a manner perpendicular to the string like a helicopter take off. Most bass string squeaks are caused by a motion similar to that of an aeroplane take off (diagonal motion).
  2. Fingertips Rotation is another effective technique to reduce the noise. The helicopter finger is useful when you are changing basses. Imagine you need to do a glissando with the bass string, you will not be able to apply the helicopter fingering in this case as you need to “hold” and slide/glide to another note. Fortunately the spot that creates the squeak is often a small area of your fingertips. To perform a Fingertips Rotation, simply rotate your fingertips ( still depressing the string against the fret) slightly to move the contact point to a softer part of your finger before you do a glissando/slide/glide. Rotate fingertips towards the sound hole for sliding to a higher note and rotate towards the nut for sliding to a lower note. Less friction means less bass string squeak or noise.

Preludio ‘Saudade’ from La Catedral
Latest 2019 Syllabus Exam Pieces for the Classical Guitar (ABRSM)

Composer: Barrios Mangoré
Preludio ‘Saudade’ is the 1st movement of La Catedral by Barrios Mangoré.

Saudade is a deep emotional state of nostalgic or profound melancholic longing for an absent something or someone that one loves. Moreover, it often carries a repressed knowledge that the object of longing might never return.
Saudade was once described as “the love that remains” after someone is gone. Saudade is the recollection of feelings, experiences, places, or events that once brought excitement, pleasure, well-being, which now triggers the senses and makes one live again. It can be described as an emptiness, like someone (e.g., one’s children, parents, sibling, grandparents, friends, pets) or something (e.g., places, things one used to do in childhood, or other activities performed in the past) that should be there in a particular moment is missing, and the individual feels this absence. It brings sad and happy feelings together: sadness for missing and happiness for experiencing the past.
Nascimento and Meandro cite Duarte Nunes Leão’s definition of saudade: “Memory of something with a desire for it.”
In Brazil, the day of Saudade is officially celebrated on 30 January.
