Punk/pop gig with female singer 2016-05-27

Couple of pictures from a gig I worked at this weekend. Pop/punk band with a female singer where the main issue was to isolate the vocals to really make them stick out through the distorted guitars and heavy drums.

This was accomplished with proper microphone placements, lining the bass and shelving EQ while at the same time boosting at 800 and around 2000 on the vocals. Very fun and rewarding experience!

Academic work: Bachelor Thesis – Analyzing Pitch 3: Cher (Pt.13)

rttrrI will be posting segments of my bachelor thesis “Out of Touch – The Framework That Is Supposedly Killing Music”. The whole essay can be found at: Link to essay

The main discussion points in the thesis are authenticity, Auto-tune and the obsession with perfection in today’s music.

Analyzing pitch: Example 2 Cher

The second example is an isolated vocal track from Cher. If compared to the Dylan-example, it could almost be mistaken for a MIDI instrument based on the lack of fluctuation and how linear it looks (figure 2.7). It is blatantly obvious that this is manipulated using one or more pitch-correcting programs. This song was the first official song to use Antares’ software Auto-tune. Interestingly enough, it was not used as the creators intended it to be used. Instead it was used as an effect, or almost as an instrument.

Looking at the curve it is almost perfect and very much exactly on the line. When the note changes the line is almost straight. On certain notes, the curve resembles the pitch of a sinus wave, meaning it is almost surely been tampered with and enhanced. This particular section is where the Auto-tune settings are maxed out. This was most likely intentional and during the chorus of the song it is not as obvious that any manipulation software is being used.

The curve shows that there is little to no vibrato. This means it was either sung with zero vibrato or that the vibrato has been manipulated with a software. It is also extremely linear, meaning the vibrato curve was most likely re-done. This statement is based on the “sinus curve sections” where it sways almost perfectly. The effect could also have been achieved using Auto-tune.

The vocals sound robotic which most likely is as a result of software manipulation. This was either achieved by using a vocoder or excessive amounts of Auto-tune or a similar software. Since it is known that Cher was using Auto-tune this is a perfect example of the many different areas Auto-tune can be used in.

When trying to automatically to add vibrato, fluctuations and variation with the program a it simply cannot be done. To attempt to give it the “human touch” a curve had to be drawn by hand. An example of what this would look like can be seen in figure 2.8. This does not sound natural and it is easy to tell that it is not an authentic performance.

Cher – Believe

Lesson 1: String Skipping in different modes

In the video I’m showing two of my absolute most used and favorite licks!

The first one is a string skip variation that is mostly in mixolydian mode. The guitar is tuned in Eb and played from a D major position.

The second one has a strong lydian feel that borders on harmonic minor on the slower sections. The lick is played from a C major position.

The tapped notes varies but sound good at the 14th, 15th and 17th fret on the high E.

Here’s a tab explaining the basis of the licks. Learn the basis of string skipping first, then add the lydian and mixolydian variations. Use your imagination to come up with more variations 🙂

Audio Engineering – Far Far Away 7-8/5 2016

Had the honor to work with the wonderful people over at Nöjesteatern in Malmö. I handled all the audio and used a relatively easy setup. The digital mixer, a Yamaha M7CL had 4 wireless mics with backups, two stagemics and an acoustic guitar. I handled all the HDD and music through a Microsoft Surface that I synced up with the script of the show. The monitor mix was basically the same except for some of the harder numbers.

Very fun! Here are a couple of picturess from the show:

Academic work: Bachelor Thesis – Analyzing Pitch: Bob Dylan (Pt.12)

The main discussion points in the thesis are authenticity, Auto-tune and the obsession with perfection in today’s music.

Analyzing pitch: Example 1 Bob Dylan

The first example is an isolated vocal track from Bob Dylan. Looking at the curve in figure 2.5 and how it fluctuates, it can be assumed that it is either a natural curve or a skillfully manipulated vibrato, added on in post process effects. In an obvious case like this, the conclusion is easy to draw and you have many different ways of establishing the authenticity of the performance.

Looking at the pitch, it is clear that it is never in perfect pitch or exactly on a specific note. On the normal, comfortable notes it is slightly above, and on the higher notes it is slightly below. This is completely normal and it also tells us that the pitch has most likely not been tampered with.

The vibrato varies from every note, which means the performer is most likely using a natural non-digitalized vibrato. It sways from the center, no matter if slightly off pitch or on pitch. In an Auto-tune scenario it would only sway from the “on-pitch”-position. The vibrato is not fixed and has a different altitude and fluctuation throughout the analyzed section.

There are no signs of anything digitalized throughout the analyzed section when listening to the track. In extreme cases it is possible to hear immediately if Auto-tune has been used.

As seen in figure 2.6 the vibrato and the fluctuations are completely removed by the pitch correction. The old curve can still be seen behind the new curve as comparison. The sound is, after the correction, completely digitalized and “sterile” but it is still possible to hear that it is Dylan. His voice is recognizable through the correction and the artifacts that make Dylan “Dylan” are still present even though the pitch is now completely on the note.

Methods for pitch analysis

To illustrate what can be achieved with the use of these three programs I have chosen three examples of music with isolated vocal tracks to analyze. To help establish whether or not the song is using Auto-tune or pitch correction I will be using three main focus points. The three most famous pitch correction software’s offer much more than just Auto-tune. They also have tools for drawing graphs, time stretching and painting melodies for further analysis. As mentioned before, pitch is a combination of different factors in sound, and these programs help identifying the pitch and giving the user the ability to manipulate it freely. This method is based partly on scientific material from “Master Handbook of Acoustics” (Everest and Pohlmann 2009), basic music theory found in “Music Fundamentals” (Takesue 2014) and the book “Vad är det jag hör” (Ternhag 2009).

The software used in the analysis is Waves Tune. Mainly because it gives a solid and easy to read representation of the graphs and curves. Both Auto-tune and Melodyne provide similar curves and graphs but with a more cluttered and hard to read result. The main points used in the analysis are the following:

  • Pitch (Takesue 2014)
    • How close to the desired note is the achieved pitch?

This is what the software is mainly used for, according to their manuals, to make sure the singer/instrument is placed correctly in pitch.

  • Vibrato (Everest and Pohlmann 2009)
    • Is the vibrato natural? Does it sway only from the middle? Is it fixed, meaning that there is no variation?

The vibrato can both be created and erased using pitch correction software. The amount of “humanity” can be regulated from inside the software, giving the curves a more non-linear line.

  • Sound (Ternhag 2009)
    • Is the sound natural, or is it obvious that it is manipulated?

The use of pitch correction software tend to give the sound and voice an un-natural feel. This is especially easy to recognize if an excessive amount is used. If pitch correction is only used on certain parts this can be hard to observe and establish.
