Sebastiaan van Bavel Trio wins Edison Award!

Het trio van pianist en componist Sebastiaan van Bavel heeft de Edison Jazz Nationaal 2014 gewonnen. Zij werden door de jury beloond voor het album ‘As the journey begins’ (O.A.P. Records) en lieten daarmee de overige genomineerden Batik en Estafest achter zich.

Pianist en componist Sebastiaan van Bavel.

De jury roemde het organische samenspel van het Sebastiaan van Bavel Trio en stelde de geleverde kwaliteit gelijk aan het legendarische trio van pianist Bill Evans met Paul Motion en Scott LaFaro.

Van Bavel won eerder twee maal het prestigieuze Prinses Christina Concours. In 2008 in de categorie jazz en in 2011 in de categorie klassiek. Van Bavels trio bestaat verder uit bassist Maciej Domaradzki en drummer Remi Troost.


New Album: Christiaan van Hemert “Time’s Up”

A new album has been released titled ‘Time’s Up’. Featuring Christiaan’s trio (Elliot Muusses on guitar and Maciej Domaradzki on bass) and special guests: Stochelo Rosenberg (guitar), Sam Pari (vocals) and Joost Swart (piano). Find it on iTunes!

Acoustic Image on Phase Invertion

An article from Acoustic Image their latest newsletter on the subject of phase invertion. Click here for the online version. If you want to know more about it, check also the incredible interview with Steve Rodby on amplifying double bass.


What’s “Phase?” And why would you want to invert it?

We recently introduced a “Phase Invert” switch on our two-channel preamp. This is a very useful feature (I’ll explain why in a bit), but it has prompted some players to ask a basic question: “What is phase and why does it need to be inverted?”

Audio signals (in fact, all periodic signals, such as radio waves) have two important characteristics: amplitude and phase. Amplitude, measured in volts, refers to the magnitude of the signal while phase, measured in degrees, is the position of the peaks and valleys of the signal relative to a fixed reference. To try to understand these concepts better, let’s take a simple sine wave signal. The figure below shows a sine wave in which the amplitude (vertical axis) is varying with time (horizontal axis):

Several cycles of the wave are shown. One cycle is the portion of the wave that includes a positive peak and a negative peak, representing 360 degrees of phase relative to the starting point of the wave (the first positive peak of the wave is 90 degrees from the start and the first negative peak is 270 degrees from the start). The frequency of the wave is the inverse of the time between positive peaks (Hz = cycles per second).

Phase can also be a relative measurement between two waves (in other words, one wave is the reference for the other). The figure below shows two waves of the same frequency that have the same amplitude. As you can see, there is a “zero” phase difference between them (their peaks line up). These waves are (you guessed it) “in phase.”

The next figure shows two waves where the peaks of one wave are lined up the valleys of the other. There is a 180 degree phase difference between them and they are, not surprisingly, said to be“out of phase.”

If the two signals of the last two examples are added together (i.e., their amplitudes are added at every instance of time), an interesting thing happens: for the in-phase signals, we get a signal with the twice the amplitude. For the two signals out of phase, the result is nothing; the two signals cancel each other out.

So you can see how phase is important. If two signals representing the same instrument are out of phase, the result can be pretty bad if both are added together. Let me illustrate by example.

I recently heard from a customer who bought a new Coda R two-channel combo to replace his older Contra one-channel combo because he liked being able to “blend” two pickups on his bass together. He found that the combination of the two gave the sound he wanted. In his email, he said that something was wrong with the new combo. “Something is missing, it just doesn’t sound like the old setup,” he said. You know where this is going. It turns out that his two pickups were out of phase with each other, and as a result, the signals were cancelling resulting in a thin sound. When I explained what was happening, he reversed the phase of one of the pickups and the result was an immediate improvement in the sound.

So, that’s why we put a phase reverse switch in each channel of our two channel combos. That switch reverses the phase of the signal by 180 degrees giving you some control of phase interactions between two pickups or a mic and a pickup.

It turns out that the phase reverse switch can also be useful in controlling feedback in a system that uses a single pickup or microphone. When standing in a certain position relative to the amplifier, it’s possible that, at a given frequency, the amplitude of signal could be at the maximum value (the peak in the examples above) in the position in which you are standing. That high amplitude could interact with the pickup or mic to cause feedback. Reversing the phase (putting the best “phase” on things?) reduces the signal at that frequency to a minimum value (the valley in the examples above), reducing the amplitude of that frequency at your position and eliminating feedback in the process.

Francois Rabbath workshop videos.

Make sure to check out the videos from the master Francois Rabbath workshop in HfM Berlin. Some great stories and insights into his revolutionary technique.

Part one of seven videos on youtube

By the way, for everyone in Holland – Lucas Suringar in Almere is selling a Rabbath style endpin which doesnt require any invasive operation on your bass, so it is a great way to check if it works for yourself. According to Rabbath it is of big benefit for your posture. I just ordered it and as soon as its here i will let you know.

Thomas Martin on Giovanni Bottesini


A fascinating read on Bottesini´s life by Thomas Martin is available on his website.

Very nice website of music journalist Anil Prasad containing some great interviews with  Ron Carter, Stanley Clark, Dave Holland, Marc Johnson, Miroslav Vitous, Eberhard Weber and many others. Definitely worth visiting.
